Synthesis and structural elucidation of cytotoxic mono and dinuclear rhenium carbonyl complexes bearing bis-{1,3-(imino pyrrolyl)-m-chloro phenyl)} ligand

A mononuclear and dinuclear rhenium tricarbonyl compounds were synthesized by the one-pot condensation reaction of [Re(CO)5Br], pyrrole-2-carboxaldehyde and 4‑chloro-m-phenylene diamine. The mononuclear rhenium tricarbonyl complex containing {3-(imino pyrrolyl)-6‑chloro phenylamine)} ligand (IPP) with formula {[Re(CO)3Br(IPP)], (1), was obtained by refluxing stoichiometric quantities of amine, aldehyde and rhenium metal precursor in methanol solution. Similarly, dinuclear rhenium tricarbonyl compound {[Re(CO)3Br]2(BIPP)], BIPP = bis-{1,3-(imino pyrrolyl)-m-chlorophenyl)}, (2) has been synthesized by refluxing appropriate amounts of aldehyde, and rhenium metal precursor in the presence of one equivalent of amine ligand. Compounds 1 and 2 were characterized by FT-IR, 1H NMR, and UV–Vis spectroscopy, elemental analysis, and mass spectrometry. The luminescence properties of the formed complexes were studied in solution at room temperature, revealing an extended lifetime for the dinuclear complex 2 in comparison to 1. DFT calculations for the optimized structures helped to understand the geometry of the complexes, whereas TD-DFT revealed the vertical transitions responsible for the photophysical properties of the complexes. The cytotoxicity of such complexes against MCF-7 breast cancer has been also reported, revealing a dose-dependent growth inhibition attributed to a DNA-intercalating mode of binding for both complexes. The pronounced effect of the two metals on the cytotoxic studies and lifetime of the excited species were investigated. The greater intercalation ability of the complex 2 in comparison to complex1 obtained from circular dichroism studies also indicates the greater efficacy of Re complex 2.

Touch initiated on-demand adhesion on rough surfaces.

Reversible adhesion with on-demand attachment and detachment is used by many animals for their locomotion. However, achieving robust and switchable adhesion on rough surfaces in artificial adhesives remains a significant challenge. Here, we present a snail mucus-inspired touch-initiate adhesive (TIA), showing robust adhesions on various surfaces. TIA is a polymeric hydrogel photo-cured with the presence of supersaturated sodium acetate (NaAc) in the precursor solution. TIA is soft and flexible at room temperature, allowing it to form conformal contact with objects with various surfaces. The contact with the target surface immediately initiates the crystallization of TIA, increasing the elastic modulus of TIA by an order of magnitude. The increased modulus and the interlocking with the target surfaces thus results in an adhesion strength up to 465.56 ± 84.05 kPa. TIA can be easily detached from the surface by heating to a temperature above 58 °C, showing an adhesion strength of 12.71 ± 2.73 kPa. The detached TIA, even cooled down to and kept at room temperature, is readily used for the subsequent adhesion. The study here not only provides a highly adhesive material for on-demand attachment to various surfaces, but also proposes a new design strategy to compose smart materials.

Artificial mucus layer formed in response to ROS for the oral treatment of inflammatory bowel disease.

The artificial mucus layer, such as hydrogels, used to repair the damaged intestinal barrier, is a promising treatment for inflammatory bowel disease (IBD). However, the currently reported hydrogel-based artificial barriers are administered via rectal injection, causing unnecessary discomfort to patients. Herein, we report an oral hydrogel precursor solution based on thiol-modified hyaluronic acid (HASH). Owing to the reactive oxygen species (ROS)-responsive gelling behavior, our precursor solution formed an artificial mucus coating over the inflamed regions of the intestines, blocking microbial invasion and reducing abnormally activated immune responses. Notably, HASH also modulated the gut microbiota, including increasing the diversity and enhancing the abundance of short-chain fatty acid-associated bacteria, which play a key role in gut homeostasis. We believe that the ROS-responsive artificial mucus layer is a promising strategy for the oral treatment of IBD.

[89Zr]ZrCl4 for direct radiolabeling of DOTA-based precursors

IntroductionZirconium-89 (89Zr) is a positron emitter with several advantages over other shorter-lived positron emission tomography (PET) compatible radiometals such as gallium-68 or copper-64. These include practically unlimited availability, extremely low cost, greatly facilitated distribution logistics, positron energy fit for medical PET imaging, and sufficiently long physical half-life to enable PET imaging at later time points for patient-specific dosimetry estimations. Despite these apparent benefits, the reception of 89Zr in the nuclear medicine community has been tepid. The driving factor for the absence of broader adaptation is mostly routed in its final formulation — [89Zr]zirconium oxalate. While serving as a suitable precursor solution for the gold standard chelator deferoxamine (DFO), [89Zr]Zr-oxalate is inaccessible for the most commonly used chelators, such as the macrocyclic DOTA, due to its pre-chelated state.Consequently, pioneering work has been conducted by multiple research groups to create oxalate-free forms of [89Zr]Zr4+, either via chemical conversion of oxalate into other counterion forms or via direct radiochemical isolation of [89Zr]ZrCl4, showing that [89Zr]Zr-DOTA complexes are possible and stable. However, this success was accompanied by challenges, including complex and labor-intensive radiochemical processing and radiolabeling procedures as well as the relatively minuscule conversion rates. Here, we report on the direct production of [89Zr]ZrCl4 avoiding oxalate and metal contaminants to enable efficient radiolabeling of DOTA constructs. MethodsWe based our direct production of [89Zr]ZrCl4 on previously reported methods and further optimized its quality by including an additional iron-removing step using the TK400 Resin. Here, we avoided using oxalic acid and effectively minimized the content of trace metal contaminants. Our two-step purification procedure was automated, and we confirmed excellent radionuclide purity, minimal trace metals content, great reactivity over time, and high specific molar activity. In addition, DOTA-based PSMA-617 and DOTAGA-based PSMA-I&T were radiolabeled to demonstrate the feasibility of direct radiolabeling and to estimate the maximum apparent specific activities. Lastly, the biodistribution of [89Zr]Zr-PSMA-617 was assessed in mice bearing PC3-PIP xenografts, and the results were compared to the previously published data. ResultsA total of 18 batches, ranging from 6.9 to 20 GBq (186 to 541 mCi), were produced. The specific molar activity for [89Zr]ZrCl4 exceeded 0.96 GBq (26 mCi) per nanomole of zirconium. The radionuclidic purity was >99 %, and the trace metals content was in the <1 ppm range. The [89Zr]ZrCl4 remained in its reactive chemical form for at least five days when stored in cyclic olefin polymer (COP) vials. Batches of 11.1 GBq (300 mCi) of [89Zr]Zr-PSMA-617 and 14.4 GBq (390 mCi) of [89Zr]Zr-PSMA-I&T, corresponding to specific activities of 11.1 MBq/μg (0.3 mCi/μg), and 14.4 MBq/μg (0.39 mCi/μg), respectively, were produced. [89Zr]Zr-PSMA-617 animal PET imaging results were in agreement with the previously published data. ConclusionIn this work, we report on a suitable application of TK400 Resin to remove iron during [89Zr]ZrCl4 radiochemical isolation. The breakthrough allows for direct radiolabeling of DOTA-based constructs with [89Zr]ZrCl4, leading to high apparent molar activities and excellent conversion rates.

The big bang of halide perovskites: The starting point of crystallization

Hybrid halide perovskites (HHPs) are very promising absorber materials for solar cells due to their high power conversion efficiency and the low-cost solution-based processing methods. We applied small angle X-ray scattering to MAPbI3, FAPbI3 and MAPbBr3 precursor solutions in different solvents (GBL, DMF, and mixtures) to gain a deeper understanding of the building blocks during the early stage of HHP formation. We present a core–shell model where the core is formed by [PbX6] octahedra surrounded by a shell of solvent molecules, which explains the arrangement of the precursors in solution and how the solvent and the halide influence such arrangement.Graphical

Improving high‐temperature capacitive energy storage of biaxially oriented polypropylene through titanium dioxide deposition layer by atmospheric pressure plasma jets

AbstractPolymer film capacitors experience a sharp decrease in charge–discharge efficiency and energy density under high‐temperature environments, which remains an urgent issue to address. In this article, atmospheric pressure plasma jet (APPJ) is used to deposit TiO2 to improve the energy storage performance of biaxially oriented polypropylene (BOPP) film in high‐temperature environment. The APPJ uses argon as the working gas and adopts a multielectrode grounding configuration to obtain the stable jet state. The precursor solution is prepared using tetraethyl titanate (TET) mixed with ethanol in a ratio of 5:3. The results show that the charge–discharge efficiency and discharge energy density (from 3.1 to 5.7 J cm–3) of BOPP films deposited by APPJ are improved at 120°C.

Large-Area Perovskite Solar Modules Based on Uniformity Engineering of Perovskite Films: The Critical Role of Methyldiphenylphosphine Oxide Additive.

Perovskite solar cells (PSCs) have led to distinguished achievements and become one of the state-of-the-art photovoltaic technologies. Undoubtedly, reliable preparation of large area high-quality perovskite (PVK) films with uniform optoelectronic properties has become a critical and challenging task to transition PSCs from lab to market. Here, methyldiphenylphosphine oxide (MDPPO) is employed as an additive in a PVK precursor solution to promote uniform conductivity and carrier transport of PVK films. More important, to check its compatibility with the upscaling process, the MDPPO additive strategy was further applied to doctor-blade large-area PVK films. As a result, benefit from the favorable role of MDPPO additive, the power conversion efficiencies (PCEs) of small-area PSCs reach 23.85% with superb open circuit voltage (Voc) of 1.15 V and fill factor of 81.21%, while an impressive PCE of 19.22% was achieved for the large-area PSC minimodules with active area of 61.48 cm2. Remarkably, the MDPPO modified device exhibits significantly improved operational stability, maintaining an initial efficiency of 68% even after 750 h under continuous 1-sun illumination. Our achievements will provide profound insight and further guidance for the scale-up process of PSCs from lab to large-scale modules.

Preparation of Highly Efficient and Stable All-Inorganic CsPbBr3 Perovskite Solar Cells Using Pre-Crystallization Multi-Step Spin-Coating Method

All-inorganic CsPbBr3 perovskite solar cells have garnered extensive attention in the photovoltaic domain due to their remarkable environmental stability. Nevertheless, CsPbBr3 prepared using the conventional sequential deposition method suffers from issues such as inferior crystallinity, low phase purity, and poor film morphology. Herein, we propose a pre-crystallization methodology by introducing a minute quantity of CsBr into the PbBr2 precursor solution to generate a small amount of CsPb2Br5 crystals within the PbBr2 film, leading to a porous PbBr2 film with enhanced crystallinity. Under the influence of more pores and CsPb2Br5 crystals as nucleation sites for inducing growth, a CsPbBr3 film with a larger crystal size, lower grain boundary density, stronger crystallinity, and higher phase purity is formed. Compared with untreated devices, photovoltaic devices prepared using the pre-crystallization method achieved a champion photovoltaic conversion efficiency (PCE) of 8.62%. Furthermore, pre-crystallized devices demonstrate higher stability than untreated ones and can still retain 94% of the original PCE after being exposed to air for 1000 h without encapsulating.

Spray technique inspired fabrication of metal-organic framework/aerogel composite for catalytic CO2 cycloaddition

Growing metal–organic framework (MOF) on the appropriate porous matrix can effectively circumvent its poor processability and recyclability owing to its powder state by providing more exposed area and enhanced stability. A feasible and efficient spray technique was applied to prepare five kinds of MOF/aerogel composites by spraying the MOF precursor droplet sequentially onto the aerogel, including carboxylate-based MOF/aerogel composites and azolate-based MOF/aerogel composites. The sprayed precursor droplets render MOF growth concentrated on the aerogel walls with resulting continuous and homogeneous MOF film, and avoid the waste of precursor solution, which is scalable with industrial potential. MOF/aerogel composites integrates the porous nature of aerogels with excellent mass transfer property and MOF film grown on aerogel walls with more active sites, which exhibit excellent catalytic activity and stability in CO2 cycloaddition.

Synthesis of LiFePO4 using adenosine triphosphate as a new organic phosphorus source and its solvothermal reaction process

LiFePO4 is prepared by hydrothermal method using phosphoric acid (named as LFP-a) or adenosine triphosphate (LFP-b) as phosphoric sources, respectively. The effects of two phosphorus sources on crystal structure, particle morphology and electrochemical properties of the materials are investigated. Meanwhile, the mechanism of adenosine triphosphate as phosphoric source to synthesis LiFePO4 is proposed. The results show that the phosphorus source has significant influence on the synthesized materials. Compared with LFP-a, LFP-b material has higher crystallinity, better particle uniformity and dispersion. This is the result of the slow release of Li3PO4 in the hydrothermal process of the ATP-dominated precursor solution, and the subsequent reaction is relatively ordered, resulting in excellent electrochemical performance: the reversible capacity at 1 C is 148.24 mAh g−1, 137.01 mAh g−1 after 100 cycles, and the capacity retention rate is 92.4 %. This work provides a reference for the preparation of high-performance LiFePO4 from organophosphorus sources.

Selective chlorine evolution reaction using Pt-RuO2 electrocatalysts in brackish water and seawater at circum-neutral pH and its application to seawater desalination

Precious metal-based mixed metal oxides have been widely used as catalysts for the chlorine evolution reaction (CER). However, a concurrent oxygen evolution reaction (OER) leads to insufficient selectivity for CER at circum-neutral pH. Herein, nanoparticulate Pt-RuO2 (PRO) is synthesized with various Pt/Ru ratios at sub-boiling temperatures, followed by post-annealing. The synthetic conditions significantly influence the physicochemical properties (crystalline structures, morphologies, surface areas, double-layer capacitance, and charge transfer resistance) and the electrocatalytic activities of CER in NaCl solutions (0.137 and 0.5 M) and seawater (with a salinity of 3.6 g L–1). Among PRO-x@y samples (where x is the mole fraction of Pt in the mixed Pt and Ru precursor solutions, and y is the annealing temperature [°C]), PRO-0.2@800 and PRO-0.8@500 show remarkable faradaic efficiencies (FEs) for CER (CER-FE). Despite their similar FEs (CER-FEs of approximately 95 % and 99 %, and OER-FEs of 4–6 % and <1 %, for PRO-0.2 and PRO-0.8, respectively), the Pt-rich PRO requires less potential for the same current density (J) and exhibits excellent stability at J = 800 mA cm–2 over 250 h in seawater at circum-neutral pH. The optimized PRO electrode is further used for seawater desalination and simultaneous production of HClO, achieving FEs of ∼100 %. Finally, various electrochemical analyses are conducted to elucidate the CER mechanism.

Thermoplastic bicomponent‐fibers for organosheets via inline polymerization

AbstractState‐of‐the‐art organosheets suffer from several shortcomings that limit their applicability in high‐performance materials, mainly due to the imperfect combination of glass fibers and polymer. To overcome these issues, a novel hybrid fiber is presented, in which every single filament consists of a glass core and an individual, thin, thermoplastic polymer coating. Those fibers can immediately be consolidated into organosheets, without the necessity of the critical combination step. Production is realized by an ultra‐rapid inline coating of the filaments, incorporated into a standard spinning system. This solvent‐free process is realized by coating of the fibers with a tailor‐made, monomeric precursor solution, which is radiation‐polymerized immediately after application. Within fractions of a second, the coating layer is thus solidified, before coiling of the hybrid fiber. Due to the very low thickness of the coating and specific formulation of the precursor, tackless layers can be achieved before the coiling, even at industrial spinning speeds.Highlights Glass fibers are coated with a thermoplast via in situ polymerization. A precursor is developed which polymerizes in 100 ms. Glass fibers are coated completely with thermoplast by using a UV tunnel. Spinning velocities of about 600 m/min can be achieved. Hybrid fibers are consolidated into glass fiber‐reinforced plastics (GFRP).

Effect of solution temperature on the microstructure of 2:17 type SmCo magnets

The exceptional magnetic properties of 2:17 type SmCo magnet material is the results of its unique cellular structure. We conducted a systematic analysis of the evolution of the solid solution temperature on the microstructure of both the solid solution precursor and the final magnet, and revealed the distribution of elements affect by the magnet's properties. The findings show that a considerable number of short-range low-order microregions are observed with discontinuous alignment orientations, and overlapping zones are produced in the solid solution precursor by low-temperature solid solutions. The aging process makes these regions challenging to organize, and a lot of 2:17 R phases form close to 1:5 H cell boundary phase and grain boundary, which impedes the enhancement of magnetic characteristics. Increasing the solution temperature promotes the diffusion of Cu and Fe elements, accelerating the ordering of the 2:17 R phase and aiding in the creation of a cellular structure. The phase evolution of the 2:17 type SmCo magnet can be better understand by referring to the previously conducted research on the impact of solid solution temperature on the microstructure of the solid solution precursor and final magnet.

Synergistic Crystallization Modulation and Defects Passivation in Kesterite via Anion-Coordinate Precursor Engineering for Efficient Solar Cells.

It has been validated that enhancing crystallinity and passivating the deep-level defect are critical for improving the device performance of kesterite Cu2ZnSn(S,Se)4 (CZTSSe) solar cells. Coordination chemistry interactions within the Cu-Zn-Sn-S precursor solution play a crucial role in the management of structural defects and the crystallization kinetics of CZTSSe thin films. Therefore, regulating the coordination environment of anion and cation in the precursor solution to control the formation process of precursor films is a major challenge at present. Herein, a synergetic crystallization modulation and defect passivation method is developed using P2S5 as an additive in the CZTS precursor solution to optimize the coordination structure and improve the crystallization process. The alignment of theoretical assessments with experimental observations confirms the ability of the P2S5 molecule to coordinate with the metal cation sites of CZTS precursor films, especially more liable to the Zn2+, effectively passivating the Zn-related defects, thereby significantly reducing the defect density in CZTSSe absorbers. As a result, the device with a power conversion efficiency of 14.36% has been achieved. This work provides an unprecedented strategy for fabricating high-quality thin films by anion-coordinate regulation and a novel route for realizing efficient CZTSSe solar cells.

Raman Study of Novel Nanostructured WO3 Thin Films Grown by Spray Deposition.

The present communication reports on the effect of the sprayed solution volume variation (as a thickness variation element) on the detailed Raman spectroscopy for WO3 thin films with different thicknesses grown from precursor solutions with two different concentrations. Walls-like structured monoclinic WO3 thin films were obtained by the spray deposition method for further integration in gas sensors. A detailed analysis of the two series of samples shows that the increase in thickness strongly affects the films' morphology, while their crystalline structure is only slightly affected. The Raman analysis contributes to refining the structural feature clarifications. It was observed that, for 0.05 M precursor concentration series, thinner films (lower volume) show less intense peaks, indicating more defects and lower crystallinity, while thicker films (higher volume) exhibit sharper and more intense peaks, suggesting improved crystallinity and structural order. For higher precursor concentration 0.1 M series, films at higher precursor concentrations show overall more intense and sharper peaks across all thicknesses, indicating higher crystallinity and fewer defects. Differences in peak intensity and presence reflect variations in film morphology and structural properties due to increased precursor concentration. Further studies are ongoing.

Improving the photoelectrochemical performance of WO3 photoelectrodes by controlling the pH and Na+ ion concentration through varying the number of H2WO4 precipitate washing treatments

In this study, WO3 thin-film photoelectrodes were grown on fluorine-doped tin oxide (FTO) substrates using the spin coating method. The H2WO4 precipitate underwent various washing treatments to prepare the Na2WO4 precursor solution, which was subsequently used for growing photoelectrodes. We found that washing with the H2WO4 precipitate changed the Na + ion concentration and pH of the precursor solution containing the H2WO4 precipitate and subsequently affected the thickness, X-ray diffraction (XRD) peak intensity, optical energy bandgap, flat-band potential, and photoelectrochemical (PEC) properties of the WO3 photoelectrode. In particular, the Na + ions in the H2WO4 precipitate solution negatively affected the PEC properties by causing photogenerated electron–hole recombination and worsening the adhesion between the substrate and the WO3 thin film. Therefore, H2WO4 precipitate washing treatment is crucial for reducing the Na + ion concentration in solutions containing H2WO4 precipitate. Consequently, among the samples grown using different numbers of washing treatments, the sample grown using 12 precipitate washing treatment cycles exhibited the highest photocurrent density of 1.37 mA/cm2 and a photostability of 97.5 %. In this study, the morphological, structural, optical, electrical, and PEC properties of WO3 photoelectrodes subjected to H2WO4 precipitate washing treatment were systematically analyzed.

In situ Blending For Co-Deposition of Electron Transport and Perovskite Layers Enables Over 24% Efficiency Stable Conventional Solar Cells.

Simplifying the manufacturing processes of multilayered high-performance perovskite solar cells (PSCs) is yet of vital importance for their cost-effective production. Herein, an in situ blending strategy is presented for co-deposition of electron transport layer (ETL) and perovskite absorber by incorporating (3-(7-butyl-1,3,6,8-tetraoxo-3,6,7,8-tetrahydrobenzo- [lmn][3,8]phenanthrolin-2(1H)-yl)propyl)phosphonic acid (NDP) into the perovskite precursor solutions. The phosphonic acid-like anchoring group coupled with its large molecular size drives the migration of NDP toward indium tin oxide (ITO) surface to form a distinct ETL during perovskite film forming. This strategy circumvents the critical wetting issue and simultaneously improves the interfacial charge collection efficiencies. Consequently, n-i-p PSCs based on in situ blended NDP achieve a champion power conversion efficiency (PCE) of 24.01%, which is one of the highest values for PSCs using organic ETLs. This performance is notably higher than that of ETL-free (21.19%) and independently spin-coated (21.42%) counterparts. More encouragingly, the in situ blending strategy dramatically enhances the device stability under harsh conditions by retaining over 90% of initial efficiencies after 250h in 100°C or 65% humidity storage. Moreover, this strategy is universally adaptable to various perovskite compositions, device architectures, and electron transport materials (ETMs), showing great potential for applications in diverse optoelectronic devices.

3D printing assisted surface patterning process on acrylated hydrogels for contact guidance of fibroblasts

Generating stable and customizable topography on hydrogel surfaces with contact guidance potential is critical as it can direct/influence cell growth. This necessitates the development of new techniques for surface patterning of the hydrogels. We report on the design of a square grid template for surface patterning hydrogels. The template was 3-D printed and has the diameter of a well in a 24-well plate. Hyaluronic acid methacrylate (HA) hydrogel precursor solutions were cast on the 3D printed template's surface, which generated 3D square shape topographies on the HA hydrogel surface upon demolding. The 3D Laser Microscopy has shown the formation of a periodic array of 3D topographies on hydrogel surfaces. 3D Laser and Electron Microscopy Imaging have revealed that this new method has increased the surface area and exposed the underlying pore structure of the HA hydrogels. To demonstrate the method's versatility, we have successfully applied this technique to generate 3D topography on two more acrylate hydrogel formulations, gelatin Methacrylate and polyethylene glycol dimethacrylate. Human neonatal dermal fibroblast cells were used as a model cell line to evaluate the cell guidance potential of patterned HA hydrogel. Confocal fluorescence microscopy imaging has revealed that the 3D surface topographies on HA hydrogels can guide and align the actin filaments of the fibroblasts presumably due to the contact guidance mechanism. The newly developed methodology of 3D topography generation in acrylate hydrogels may influence the cell responses on hydrogel surfaces which can impact biomedical applications such as tissue engineering, wound healing, and disease modeling.

Effect of Methylammonium Iodide (MACl) on MAPbI3-Based Perovskite UV-C Photodetectors

In this study, we fabricated deep ultraviolet (DUV) photodetectors based on perovskite thin films doped with halide materials using formamidinium bromide (FABr) and methylammonium iodide (MAI). The device was fabricated using a simple surface engineering technique by post-treating the MAPbI3 perovskite film with an FABr solution. This film acts as a light absorption layer, like a depletion layer with a p-i-n (PIN) structure, with n-type of SnO2-SDBS and p-type of spiro-OMeTAD. Adding 0.10 M MACl to the MAPbI3 precursor solution during the manufacturing process could effectively reduce the trap density compared with existing films. Films with MACl added in the two-step process can control a wide band gap and improve crystallinity. In addition, the Cl atom has a smaller atomic radius than iodine and a higher electronegativity of 3.16, which can improve phase stability, and the effect of the added Cl− increases the electron mobility of the perovskite, showing a fast response.

Latent fingerprint imaging using irradiated novel mixed metal oxides (MXOY, M=Ba, Zn, Al, Ce) nanophosphor.

Latent fingerprint developed at the site of crime is considered as crucial physical evidence in forensic investigation. The mixed metal oxides (MXOY, M=Ba, Zn, Al, Ce) nanophosphor was synthesised by irradiating the precursor solution with 60Co gamma radiation followed by solution combustion method. The structural, morphological, optical characteristics and fingerprint imaging were studied using X-ray diffraction (XRD), scanning electron microscopy, UV-visible spectroscopy and powder dusting method, respectively. The XRD results revealed that the average crystallite size is found to be 30nm with the estimated bandgap of 3.18eV. The broadband UV exited luminescence of the phosphors was observed at λMax=330nm. The PL spectrum shows three emission bands at 432, 444 and 460nm that corresponds to blue regions, suggesting that the synthesised nanophosphor is a potential luminous material for latent fingerprinting and luminescent devices.
