Optimizing Electron‐Beam Photothermal Pyrolysis Parameters for Enhanced Molecular Biodegradability of Polyvinyl Chloride Plastics

AbstractPolyvinyl chloride (PVC), a synthetic plastic notable for harmful emissions during deterioration, has potential to be molecularly adjusted by photo‐oxidative ultraviolet degradation. This research investigates the influence of electron beam irradiation and near‐infrared photothermal treatment utilizing gold nanoparticles to establish the optimized molecular weight and beam time exposure for biodegradable PVC properties while maintaining a minimum tensile strength as measured through the ratio of peak tension force by cross sectional area. PVC powder samples with number‐average molecular weights ranging from 20.0 to 90.0 kDa and varying exposure times of a 100 kGy electron beam from 80 to 115 ms are employed for the study. Outcomes from PVC irradiation reveal the optimal parameters for inducing biodegradability in samples: an e‐beam exposure duration of 95 ms applied to PVC powder with a sample molecular weight of 20.0 kDa. Analysis of the ratio of number average molecular weight and weight average molecular weight demonstrates that shorter irradiation durations result in lower molecular weights and molecular weight is directly proportional to Tg and crystallinity. Future work aims to scale up the procedure to industrial applications and investigate the treatment's applicability to a variety of thermoplastics.

Glycosylated gelatin prepared based on electron beam irradiation and its physicochemical properties

The influence of electron beam irradiation (EBI) treatment on the modification of gelatin-galactose glycosylation was thoroughly examined. The results of the degree of grafting and browning revealed that EBI triggered the glycosylation reaction of gelatin. The degree of glycosylation exhibited a gradual increase with the rising irradiation dose, reaching a maximum of 25 kGy. Moreover, the irradiation process opened up gelatin's internal structure, exposing its hydrophobic groups. This exposure led to an enhancement in sample surface hydrophobicity. The fluorescence intensity at the maximum emission wavelength of the fluorescence spectra decreased; Fourier infrared spectroscopy demonstrated a new absorption peak at 1074 cm−1 for the glycosylation product. These findings substantiate that gelatin formed a new product through covalent bonding with galactose. Glycosylation boosted the emulsification stability of gelatin from 1.92 min to 10.42 min and improved its emulsification and rheological properties. These outcomes affirm that EBI can effectively induce the glycosylation reaction of gelatin, thereby enhancing its functional properties. In addition, EBI has the potential to supplant the conventional heating glycosylation method. This study lays a solid theoretical foundation for the future application of glycosylation and gelatin.

Dual role of CoO and electron beam irradiation in enhancement the transport properties of borate glasses

The synthesis of lithium borate cadmium glasses doped with cobalt oxide (CoO) (LiBCdCo) was achieved using the traditional melt-quench process. The chemical composition of the glasses was determined to be 12 % Li2O – 5 % CdO – (83-z)% B2O3, where z represents the mol% of CoO and ranges from 0.0 to 2. Various experimental approaches, such as X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), Raman spectroscopy, FTIR and electrical measurements, were employed to investigate the physical, structural, and electrical properties. XRD patterns obtained from the manufactured glass specimens revealed their amorphous nature. The EDX analysis provides insight into the exact chemical composition of the materials in their prepared form. Raman spectroscopy and FTIR analysis have been employed to verify the disparity in the chemical bonds present in lithium borate cadmium glasses, both in their undoped state and when doped with 2 % CoO. The study observed a decrease in density and oxygen packing density as the molar ratios of the modifier oxides in the produced glasses increased. The present study investigates the electrical conductivity and dielectric properties of the glass samples manufactured, focusing on the influence of electron beam irradiation (E.B.). The investigation revealed that the samples exhibited greater effects when exposed to higher doses (100 kGy) of electron beam irradiation. This can be attributed to the increased occurrence of defects, specifically the formation of non-bridging oxygen species (NBOs). The ac-conductivity measurements indicate that the correlated barrier hopping (CBH) mechanism is the most suitable explanation for the ac-conduction behavior observed. This mechanism involves the electron conduction in the CoO-doped glass samples through the hopping of electrons between relaxation sites. This conduction process is facilitated by the conversion of BO3 units into BO4 units and the reduction of cobalt ions from Co+2 to Co+3.

Influence of electron beam irradiation induced charging-effect on nanoprobing localization of a crystal defect in MOSFET

The paper demonstrates that the electron beam (e-beam) irradiation induced charging-effect has remarkable impact on nanoprobing localization of a crystal defect hidden in metal-oxide-semiconductor field-effect transistor (MOSFET). We present a practical example showing that device characterization at the contact layer (CT) is susceptible to the charging-effect since scanning electron microscopy (SEM) based nanoprobe system running is inevitablely acompanied by e-beam irradiation towards device under test (DUT). The mechanisms is seldomly reported in the past. In our case, the p-n junction at a nMOSFET drain end showed the ohmic current-voltage (I-V) characteristic at the beginning. However, by utilizing the atomic force microscopy (AFM) based nanoprobe system without e-beam, the measurement found previous resistive characteristic of the p-n junctions disappeared. Instead, it exhibited good rectifying characteristic. I-V characteristic discrepancy coming from two analytical methods was attributed to the charging-effect influence. It was experimentally proven that the charging-effect impact at MOSFET gate CT had strong dependance on the e-beam irradiation magnitude corresponding to the SEM scan speed. Charging effect produced distinct consequences at distinct scan speeds. The positive charging-effect occurred under the fast scan while the negative charging-effect occurred under the slow scan. The former mechanism made the potential at gate CT high enough to turn on nMOSFET. Therefore, the nMOSFET channel current merged with the p-n junction current in a closed-loop. In contrast, the slow scan induced negative charging-effect made the gate potential lower than the nMOSFET threshold voltage (VT), so that the nMOSFET stayed off-state. Consequently, the p-n junction resumed its intrinsic rectifying I-V characteristic. Different from the nMOSFET, the charging-effect affected the pMOSFET in the opposite manner. As a result, the initial conclusion of the MOSFET junction leakage was not valid. Next, we ran a optimal flow to narrow down a fault by eliminating the charging-effect impact. Eventually, a crystal defect (pipeline) was isolated in a suspcted nMOSFET relying on nanoprobe and TEM analysis. The article explains the evident influence of charging-effect on the nanoprobe analysis and puts forward an effective way to minimize the side effect of the e-beam irradiation. The work may draw more attention to the analytical methodologies regarding MOSFET reliability improvement.

Study of the influence of electron beam irradiation on the microstructural and mechanical characteristics of titanium-coated Al-Si alloy

The present study aims to study the effect of change in beam energy density on microstructural features and mechanical behavior. The results show that the beam energy density value influences Ti coating layer particles. The microstructural studies indicate the presence of nanocrystalline columnar structure and eventually lead to the transformation of cellular structure with the increase of beam energy density. With the increase of beam energy density, metallurgical defects on the original surface, including micropores and elemental segregations, were eliminated, and a remelted layer consisting of the high density of cross slips and nanostructures was obtained. At lower beam energy density, Al-based solid solution was formed, but the decrease of the lattice parameter of Al was observed with the increase of beam energy density, which may be attributed to the doping of Al with Si and Cu atoms. Lower yield strength among all samples was obtained for a sample treated at 50 J/cm2, which is 40 % less than the as-fabricated alloy. The ultimate tensile strength was initially increased for the sample treated at 20 J/cm2, but ultimate tensile strength was decreased for all remaining samples on an average of about 6–8 %.

The electron beam induced cross-linking of bovine collagen gels with various concentrations: The mechanical properties and secondary structure

This study considered the examination of the influence of electron beam irradiation (2 and 100 kGy) on bovine collagen gels with various concentrations (3, 6 and 8 wt%). The impact of irradiation was verified via the analysis of the mechanical properties and the secondary structure of the collagen. The irradiated collagen gels behaved non-linearly and stiffened with increasing strain in contrast to the non-irradiated state in which they softened with increasing strain. The impact of irradiation was reflected by an increase in the tensile modulus and strain energy density. The observed increase was greater the higher the water content of the collagen gels. The impact of irradiation on the secondary structure was less clear; infrared spectrometry revealed that the events that take place are complex, with the occurrence of cross-linking, partial denaturation and other structural changes. The electron beam irradiated collagen gels continued to exhibit collagenous polymeric structures and integrity.

Influence of electron beam irradiation on nanoscale adhesion during colloidal probe experiments inside the scanning electron microscope

Scanning electron microscope is not only a versatile visualization and characterization tool for nanomaterials, but it is also widely used for visual feedback during assembly and manipulation of micro- and nanoparticles, novel devices based on 2D and 1D materials, and microrobots. Due to increase in the surface-to-volume ratio, adhesion forces play a significant role in micro- and nanorobotic applications. We investigate the quantitative effect of electron beam irradiation on nanoscale adhesive interactions between different end effector types and plain substrates. For this purpose, we use an interferometry-based force measurement setup integrated into the chamber of a scanning electron microscope capable of a subnano Newton force resolution. We provide quantitative results for the influence of the electron beam on the adhesion forces depending on the exposure dose, geometrical configuration in which it is applied, as well as on the material of the end effector. Simulation results, atomic force microscope adhesion measurements, and measurements with piezoresistive cantilevers serve as references. Our findings indicate that the electron beam influences the adhesive interaction not only in the case of insulating probes but also for well-grounded conducting and semiconducting probes. Its influence can range from several 10% to several 100% in comparison to the adhesion values measured with an atomic force microscope in an ambient atmosphere and no charged particle beam is applied. Moreover, it is shown that the influence of a charged particle beam is a multidimensional phenomenon that depends on several factors such as end effector and substrate material, geometry and aspect ratio of the end effector, geometrical configuration between particle beam and probe–sample arrangement, as well as exposure dose and field of view. We provide recommendations for handling and characterization of micro- and nano-objects using end effectors under the influence of charged particle beams: not to rely on adhesion values acquired in different environmental and exposure conditions, not to expect the application of conductive materials and grounding to completely avoid the effect of charged particle beams, and to be aware that charged particle beams can lower or increase the adhesion force in vacuum depending on material properties, among others.

Study on the Influence of Electron Beam Radiation Sterilization Method on Chinese Mural Pigment

Murals are one of the important cultural heritages of mankind. The microbial control of murals is an important subject in mural painting conservation. In recent years, electron beam radiation sterilization has attracted more and more attention in the field of cultural relic protection. Murals are immovable cultural relics, so conventional electron beam irradiation equipment can not be used. However, the development of small mobile electron beam irradiation equipment shows the potential of radiation’s application in the sterilization protection of immovable cultural relics such as murals. A feasibility study of radiation sterilization in mural paintings is needed to investigate the effect of sterilization and the influence of sterilization dose on the stability of mural painting pigments and bonding materials. In this paper, the radiation effects of typical bacteria in tomb murals and mineral pigment powder in ancient Chinese paintings were studied in a laboratory. Firstly, aeromonas hydrophila (Aer.h) and penicillium flavigenum (PNC) were selected as representative strains to determine the appropriate sterilization dose for murals. Then, the effects of radiation on seven kinds of ancient Chinese mineral pigments and white calcium carbonate in the ground layer were verified. The results are as follows: the radiation dose of 10 kGy can effectively remove the two typical strains. This sterilization dose will cause a color difference in calcium carbonate and lead white, while other color pigments are essentially stable. Based on the color difference and UV-vis intensities of the four white carbonate samples, the color change in two of them increased with increasing the dose up to 30 kGy, after which signs of saturation began to appear. X-ray diffraction (XRD), Raman spectra, X-ray photoelectron spectroscopy (XPS) and X-ray absorption near edge structure (XANES) spectra showed that the chemical structure of the samples did not change after irradiation. The formation of free radicals in treated samples was confirmed using an electron paramagnetic resonance (EPR) spectrum test. According to all characterization results, the color difference between the four white carbonate samples may be due to the combination of unpaired electrons and defects in the process of electron beam irradiation to form color centers. After forming the color center, the light absorption of the four samples changed. This is a reversible change, but the samples will take a long time to return to their original state. This study focuses on the influence of electron beam radiation on pigment composition, which is a preliminary exploration of whether radiation sterilization can be applied to the protection of ancient Chinese mural paintings, and the experimental results can provide basic data for later application.

Mechanism of electron beam irradiation on the lipid metabolism of paddy during high temperature storage

Electron beam irradiation (EBI) is widely used in paddy storage to prolong the storage period. Paddy deteriorated easily in high-temperature environments. Lipids are most closely related to the deterioration of paddy quality, but the influence of EBI on lipid metabolism in paddy is still unclear. In this study, we aimed to reveal the mechanism by which EBI treatment prolongs the storage period of paddy by characterizing lipidome changes in high-temperature environments. The results showed that compared with untreated paddy, EBI significantly reduced the free fatty acid level, peroxide value, and content of fatty acid components in paddy. Lipid metabolism is one of the most important reasons for the deterioration of paddy quality. EBI can decrease the activity of lipid metabolism-related enzymes during storage. Finally, the lipidomics of paddy were analyzed, which clarified that EBI delayed lipid deterioration by inhibiting phospholipid and fatty acid metabolism pathways in paddy. Overall, the results indicate that EBI treatment could slow lipid metabolism and oxidation in paddy to prolong the storage period. They also provide technical guidance for promoting and applying EBI to paddy storage.

Efficient removal of reactive red 24 from aqueous solution through electron beam and aeration tank using response surface methodology

The present work examines the decolorization of reactive red 24 (RR24) from an aqueous solution via the electron beam (EB) and aeration method. Response surface methodology (RSM) with central composite design (CCD) was used to optimize the treatment with the four selected variables, i.e., absorbed dose, H2O2 concentration, initial pH (in EB system), and operation time (in the aerobic reactor). The predicted optimized conditions for the color removal were 4.5 kGy for absorbed dose, 4.0 mM for H2O2 concentration, 6 for initial pH, and 7.5 days for operation time. The experimental response of 97.14% color removal from these optimized conditions was in agreement with the value predicted by the model to within an error of 2.24%. The closeness of the predicted values and experimental results indicated that the quadratic model is adequate for predicting the decolorization process of coupled EB and aeration. Besides, modern density function theory (DFT) and natural bond orbital (NBO) calculations are also used to predict the decomposition reaction mechanism of RR24 under the influence of EB irradiation. This study demonstrated a practical method of eliminating reactive dyes by the hybrid of EB and biological methods.

Structural evolution of low-dimensional metal oxide semiconductors under external stress

Abstract Metal oxide semiconductors (MOSs) are attractive candidates as functional parts and connections in nanodevices. Upon spatial dimensionality reduction, the ubiquitous strain encountered in physical reality may result in structural instability and thus degrade the performance of MOS. Hence, the basic insight into the structural evolutions of low-dimensional MOS is a prerequisite for extensive applications, which unfortunately remains largely unexplored. Herein, we review the recent progress regarding the mechanical deformation mechanisms in MOSs, such as CuO and ZnO nanowires (NWs). We report the phase transformation of CuO NWs resulting from oxygen vacancy migration under compressive stress and the tensile strain-induced phase transition in ZnO NWs. Moreover, the influence of electron beam irradiation on interpreting the mechanical behaviors is discussed.

Terahertz spectroscopic analysis of non-radiated and radiated synthetic and natural polymer / GO nanocomposites

Absorption coefficient, refractive index, and dielectric parameters of two sets of polymers: synthetic polymers (poly acrylamide, and poly vinyl alcohol), and natural polymers (chitosan, and cellulose acetate) have been investigated using Terahertz time-domain spectroscopy THz-TDS in the frequency range of 0.3 THz - 3.0 THz. It is found that these parameters are significantly boosted by the presence of graphene oxide (GO) as a filler. The influence of electron beam radiation of a dose of 50 kGy on the absorption coefficient, and refractive index is also investigated. An observable decrease in these parameters is illustrated in the un-doped and doped membranes upon irradiation. By this study, we shed light on how the THz-TDS is able to identify any variant change in the structure due to incorporation of GO or as an influence of electron beam radiation.

Influence of electron beam irradiation on extracellular matrix of the human allogeneic skin grafts.

The nonviable allogeneic human skin grafts might be considered as the most suitable skin substitutes in the treatment of extensive and deep burns. However, in accordance to biological security such grafts require the final sterilization prior to clinical application. The aim of the study was to verify the influence of electron beam irradiation of three selected doses: 18, 25, and 35 kGy on the extracellular matrix of human skin. Prior to sterilization, the microbiological tests were conducted and revealed contamination in all examined cases. Individual groups were subjected to single electron beam radiation sterilization at proposed doses and then subjected to microbiological tests again. The results of microbiological testing performed for all irradiation doses used were negative. Only in the control group was a growth of microorganisms observed. The FTIR spectrometry tests were conducted followed by the histological evaluation and mechanical tests. In addition, cost analysis of radiation sterilization of individual doses was performed. The results of spectroscopic analysis, mechanical tests, and histological staining showed no significant changes in composition and characteristics of tested tissues after their irradiation, in comparison to control samples. The cost analysis has shown that irradiation with 18 kGy is the most cost-effective and 35 kGy is the least favorable. However, according to biological risk reduction, the recommended sterilization dose is 35 kGy, despite the higher price compared to the other doses tested.

Induction of novel variants in Chrysanthemum morifolium through electron beam radiation

Un-rooted cuttings of chrysanthemum varieties Pusa Chitraksha, Pusa Anmol and Basanti were treated with Electron Beam (EB) radiation (20 Gy and 30 Gy) with an objective of inducing variability and evaluated at ICAR-DFR, Pune during 2020. A gradual and significant reduction in vital plant growth parameters was observed with increase in doses. Influence of EB radiation (at 30Gy) on plant height (-34.55%), plant spread (-28.60%), internode length (-39.04%), leaf length (-26.95%), leaf width (-29.28%), number of flowers per plant (-23.28%) and for flower diameter (-24.80%) in comparison to control was recorded. Delay in days to bud initiation and flowering at higher dose (30 Gy) were 13.47 days and 17.33 days, respectively over control. Among the varieties, Pusa Chitraksha was found superior for most of the vegetative growth and flowering parameters. However, it exhibited delay in bud initiation (95.80 days) and flowering (118.0 days). The trend is similar for other two varieties at higher dose. In the interaction effect (Variety x EB dose), plant height (17.00 cm) was very less in variety Basanti at 30 Gy dose. Flower diameter (3.26 cm) was reduced with increased EB dose (30 Gy) in Pusa Aditya compared to control (5.24 cm). Pusa Chitraksha exhibited variation in flower colour (Magenta to white/ cream colour) and Pusa Aditya produced red colour flower at 30 Gy. Based on the study, it can be inferred that Electron Beam at 20-30 Gy had potential to create variation in chrysanthemum.

Impact of electron beam irradiation in potato starch films containing hibiscus aquous extract

The development of starch films containing natural antioxidants is one alternative of active packaging. Starch is a well-studied natural biopolymer that can be used for the development of biodegradable films because it presents a low cost, is easy to obtain and presents good ability to form films. Hibiscus sabdariffa, commonly known as hibiscus, roselle or red sorrel, is an annual herbaceous sub shrub that contains many types of biocompounds, including organic and phenolic acids. The aim of the present work was to determine the influence of electron beam irradiation on potato starch film containing hibiscus extract. The aqueous hibiscus solution was prepared by boiling for 3 min 1% w/ml dehydrated hibiscus flowers in 500 ml deionized water. The film forming solution was prepared by casting (5% potato starch, 3% glycerol as plasticizer and the hibiscus solution) and irradiated in a 1.5 MeV electron beam accelerator Dynamitron II (Radiation Dynamics Inc.), with doses of 0, 20, 40 and 60 kGy. After drying some mechanical properties were measured. The tensile strength of the control films and the irradiated ones was established. There were no significant differences among them. It looks like hibiscus antioxidants were able to prevent the expected starch radiation degradation process caused by radiation generated free radicals.

Study on surface modification of silicone rubber for composite insulator by electron beam irradiation

In order to improve the outdoor service life of composite insulators, the effect of electron beam irradiation on SIR is studied. In this paper, the silicone rubber was treated by two different doses of electron beam irradiation, and the accelerated aging test of 1000 h high temperature, high humidity and strong sunlight was carried out in the multi factor aging test chamber. At the same time, the physical and chemical properties such as physical tensile properties, hydrophobicity, optical microscope, scanning electron microscope (SEM), Attenuated Total internal Reflection Fourier Transform Infrared Spectrometer(ATR-FTIR) and crosslinking density were analyzed. The results showed that after low electron beam irradiation dose (40 kGy) treatment, the crosslinking density of silicone rubber increased by 8.8 times, and after 1000 h aging treatment, the crosslinking density of low irradiated(40 kGy) silicone rubber is still 6 times higher than that of unirradiated silicone rubber. Based on the analysis of the test results, the surface modification mechanism of silicone rubber under electron beam irradiation and aging is proposed. The research observation results demonstrate the influence of electron beam irradiation and aging on silicone rubber. Related research provides a novel idea for improving the service life of insulators.

Study of crystallization behaviour of electron beam irradiated polypropylene and high-density polyethylene.

The influence of electron-beam irradiation on polypropylene (PP) and high-density polyethylene (HDPE) was investigated with a focus on crystallization. A high-temperature (200°C) creep test revealed that the HDPE gradually increased cross-linking density in the range 30–120 kGy, while the PP underwent a chain scission which was quantitatively evaluated by gel permeation chromatography. The mechanical properties were measured in the range -150 to 200°C by a dynamic mechanical analysis. A small presence of C=C and C=O bonds was found in the irradiated PP by a Fourier transform infrared spectroscopy. Crystallization kinetics measured by differential scanning calorimetry and hot-stage optical microscopy results were influenced tremendously by irradiation for HDPE and to a lesser extent for PP. Irradiation caused a decrease in both the number of nucleation centres and the growth rate of individual spherulites. Crystallization was analysed in detail with the help of Hoffman–Lauritzen, Avrami and Arrhenius equations. Interestingly an increasing β-crystal formation with an increasing irradiation level was discovered for PP by X-ray diffraction. A generation of defects in the crystalline structure owing to irradiation was discussed.

Influence of electron beam irradiation on nitrogen-saturated biodiesel

The objective was to study changes in nitrogen-saturated biodiesel irradiated by electron beam and to analyse them considering the influence of absorbed dose. Based on the obtained results, it can be concluded that irradiation in presented condition did not affect ester groups in fatty acid methyl esters (FAME) molecules, but slightly influenced on double bonds. After irradiation was observed relatively small change in concentration of methyl esters. Slightly influence can be explained by absorption of radiation by nitrogen present in samples. Therefore, the use of ionizing radiation to improve Rapeseed Methyl Esters (RME) properties can be used only in specific radiation dose range (total ester concentration must not be lower than 96.5 wt%). The reduction in the total concentration of methyl esters was lower than after irradiation of FAME samples saturated with water and air, which was presented in previous works.

In Situ Study of the Wet Chemical Etching of SiO2 and Nanoparticle@SiO2 Core-Shell Nanospheres.

The recent development of liquid cell (scanning) transmission electron microscopy (LC-(S)TEM) has opened the unique possibility of studying the chemical behavior of nanomaterials down to the nanoscale in a liquid environment. Here, we show that the chemically induced etching of three different types of silica-based silica nanoparticles can be reliably studied at the single particle level using LC-(S)TEM with a negligible effect of the electron beam, and we demonstrate this method by successfully monitoring the formation of silica-based heterogeneous yolk–shell nanostructures. By scrutinizing the influence of electron beam irradiation, we show that the cumulative electron dose on the imaging area plays a crucial role in the observed damage and needs to be considered during experimental design. Monte-Carlo simulations of the electron trajectories during LC-(S)TEM experiments allowed us to relate the cumulative electron dose to the deposited energy on the particles, which was found to significantly alter the silica network under imaging conditions of nanoparticles. We used these optimized LC-(S)TEM imaging conditions to systematically characterize the wet etching of silica and metal(oxide)–silica core–shell nanoparticles with cores of gold and iron oxide, which are representative of many other core–silica–shell systems. The LC-(S)TEM method reliably reproduced the etching patterns of Stöber, water-in-oil reverse microemulsion (WORM), and amino acid-catalyzed silica particles that were reported before in the literature. Furthermore, we directly visualized the formation of yolk–shell structures from the wet etching of Au@Stöber silica and Fe3O4@WORM silica core–shell nanospheres.

Modifications of structural and optical properties of nanophase BaWO4 phosphors: Dose dependent effect of high energy electron beam irradiation

The present work reports dose dependent influence of 8 MeV electron beam irradiation on the structural and optical properties of BaWO4 nanoparticles fabricated by chemical precipitation route. The synthesized materials were calcined at 400 °C for 3 h to get well defined nanocrystalline particles. The calcined materials were irradiated by 8 MeV electron beams of different doses and studied the influence of irradiation on the structural and optical properties of BaWO4 nanoparticles using various characterization tools. The structural studies revealed modifications of lattice parameters a and c, unit cell volume, d spacing, crystallite size, micro-strain, and peak shift for major peaks of X-ray diffraction patterns of the electron irradiated samples. The electron irradiation also results some defects in the crystal lattice of BaWO4 nanocrystals upon electron beam irradiation. Scanning electron microscopic images demonstrated mesoporous behaviour of the BaWO4 materials. The optical studies established that optical bandgap and intensity of photoluminescence emission can be modified by using electron irradiation technique for potential applications in electronics. Photoluminescence emission properties of BaWO4 phosphors suggest that they are useful for the construction of near ultraviolet light excited blue light emitting diodes. Results explored from the present work constitute the first report for the dose-dependent influence of electron beam irradiation on the structure, optical absorption and photoluminescence properties of BaWO4 nanoparticles.
