Effects of Gamma Irradiation on Optical Properties of Poly(ethylene oxide) Thin Films Doped with Potassium Iodide

In this study, the effect of gamma irradiation on the optical properties of thin films of polymer electrolytes was investigated. The thin films were composed of poly(ethylene oxide) (PEO) doped with different concentrations of potassium iodide (KI) salt. The optical absorption spectrum of each film was measured using a UV–Vis spectrophotometer over a range of 300 to 800 nm. The PEO thin-film samples were subjected to gamma irradiation at two different doses of 100 and 200 Gy generated by a Co-60 source. It was found that the optical properties of the thin films were significantly influenced by the KI dopant concentration and gamma irradiation. Increasing both the KI concentration and the gamma irradiation dose resulted in a reduction in the energy gap and an increase in the absorption coefficient, extinction coefficient, refractive index, and dielectric constant of the PEO electrolyte. These findings have potential applications in the optimization of polymers for use in optical devices and energy storage systems.

Impact of Ag Nanoparticles on the Spectral and Optical Properties of Electrospun Nanofibrous Poly(vinyl alcohol)–Poly(acrylamide)

Nanofibers based on the polymer mixture that was associated with poly(vinyl alcohol) (PVA) and poly(acrylamide) (PAAm) (50/50 wt.%) doped with different ratios of silver nanoparticles (Ag NPs) were successfully synthesized using electrospun method, which was performed at room temperature (RT) and high voltage (12 kV). The products were studied using techniques including scanning electron microscopy (SEM), atomic force microscopy (AFM), Fourier transform infrared (FTIR), X-ray diffraction (XRD) and ultraviolet–visible absorption spectroscopy. SEM results show uniform structures and a smooth surface without particles visible on the surface of the nanofibers. Also, SEM images show that the average diameter of polymer blend nanofibers is 157.40 nm and decreases with the increasing concentration of Ag NPs. The small capacity of the carbonyl group to operate as a powerful electron donor for interacting with [Formula: see text] cation is shown by the fact that the FTIR signal strength decreases with increasing dopant concentration, indicating an increase in the basicity of the major functional groups. The X-ray diffraction pattern results confirm the amorphous nature (nano-crystalline) of the PVA–PAAm. The XRD results show that the crystallite size increases with the increase of the concentration of Ag and the peaks of weak intensity at a concentration of 6% agree with Ag in the cubic structure. Indirect allowed and forbidden transition optical energy gap values decreased with increasing Ag NPs content. The effect of doping on the other parameters (absorption coefficients, refraction index and extinction coefficient) of different blend behavior was investigated in detail which qualifies them for solar cell applications.

Effect of surface termination on electronic and optical properties of lead-free tin-based eco-friendly perovskite solar cell: a first principal study.

The lead (Pb)-based halide perovskites have been reported to be promising materials for photovoltaic applications; however, the presence of toxic lead in them concerns the environmental and health issues. In this work, we have, therefore, studied the lead-free and non-toxic tin-based halide perovskite, CsSnI3, which is an eco-friendly material with high power conversion efficiency, thus, being a potential candidate for photovoltaic applications. We have investigated the influence of CsI and SnI2-terminated (001) surfaces on structural, electronic and optical properties of lead-free tin-based halide perovskite CsSnI3 from the first principal calculations, based on density functional theory (DFT). The calculations of electronic and optical parameters are performed under the parameterisation of PBE_Sol for exchange-correlation functions conjugated with modified- Beche-Johnshon (mBJ) exchange potential. The optimised lattice constant, the energy band structure and the density of states (DOS) have been calculated for the bulk and different terminated surface structures. The optical properties of CsSnI3 are computed in terms of the real and imaginary part of absorption coefficient, dielectric function, refractive index, conductivity, reflectivity, extinction coefficient and electron energy loss. The photovoltaic characteristics for the CsI-termination are found to be better than the bulk and SnI2-terminated surfaces. This study reveals that optical and electronic properties can be tuned by selecting proper surface termination in halide perovskite CsSnI3. The CsSnI3 surfaces exhibit semiconductor behaviour with a direct energy band gap and a high value of absorption power in the ultraviolet and visible region, rendering these inorganic halide perovskite materials important for the eco-friendly and efficient optoelectronic devices.

Inhibitory effects of water mist containing alkali metal salts on hydrogen–natural gas diffusion flames

Fire extinguishing technologies of fine water mist containing additives have good application prospects. Additives that are efficient, nontoxic, nonpolluting, widely used, economical and reliable provide a reference for the application and promotion of fine water mist fire extinguishing systems containing alkali metal salts. In this paper, six potential alkali metal salt additives were selected: potassium carbonate (K2CO3), sodium carbonate (Na2CO3), potassium oxalate (K2C2O4·H2O), potassium acetate (CH3COOK), potassium chloride (KCl), and potassium bicarbonate (KHCO3); these additives were delivered into the fires as mists of their solutions at certain concentrations, the extinguishing time was recorded, and the minimum fire extinguishing concentration (MEC) of fine water mist containing alkali metal salt was tested by using a cup burner experimental apparatus. In addition, different types of alkali metal salts were compared to determine the anions and cations with better fire suppression performance levels. The suppression efficiencies of different ratios of additive packages for hydrogen-doped natural gas diffusion flames were studied to determine a specific ratio of additive packages. Based on the results of the experiment, in contrast to the pure water mist, the suppression efficiency of alkali metal salt greatly improved. The cation extinguishing ability was K+>Na+, and CO32- and CH3COO− were better than other anions in alkali metal salts. An efficient compound additive was identified as 1.5% K2CO3 + 0.5% CH3COOK. With increasing hydrogen addition, the MEC of fine water mist with additives increased.

Effect of thickness on structural, optical, and optoelectrical properties of sprayed CuInSnS4 thin films as a new absorber layer for solar cells

Thin CuInSnS4 films, CITS of different thicknesses have been synthesized by spray pyrolysis method for the first time. These films have been deposited on pre-cleaned soda-lime glass substrates. X-ray diffraction, XRD, energy dispersive X-ray analysis, EDX, and field-emission-scanning electron microscope techniques have been utilized to characterize these CITS films. XRD-studies affirmed the polycrystalline nature of films, in addition EDX-analysis of films proves that they are stoichiometric films. Spectrophotometric studies indicate that the optical bandgap energy of films decreased from 1.88eV to 1.63eV and arose from direct allowed transitions; on contrary, the Urbach energy increases from 58 meV to 73 meV as film thickness increases. Increasing the thickness also leads to increase the absorption coefficient, extinction coefficient, and refractive index of films. Dielectric constants, and optical and electrical conductivities, along with the dispersion energies have been estimated and discussed. The dispersion energy increased (13.29eV–16.76eV), while the oscillator energy decraeses (2.98eV–2.53eV). Some linear and nonlinear optical parameters of films have been also investigated. Hot probe procedure was employed to check the semiconductor type of CuInSnS4 layers, which reveals that films have p-type conductivity. Obtained findings demonstrate that CuInSnS4 layers can be utilized as a new absorber layer for solar cells.

Impact of substrate -target distance on the hemispherical expansion plume generated by the deposit of SnSe nanoparticle thin films

The pulsed laser deposition technique utilised to deposit SnSe thin films on quartz substrates utilises Nd:YAG laser at the temperature of 573 ​K with different substrate–target distances (Ds-t) of 2, 2.5, 3 and 3.5 ​cm. X-ray diffraction of the thin films revealed an orthorhombic phase with a polycrystalline structure. Crystallite size decreased when Ds-t increased. Field emission scanning electron microscopy showed the film morphology and revealed the formation of spherical and nanorod structures with increasing Ds-t. The energy band gap calculated from transmittance data increased in the range of 1.71–3.65 ​eV with increasing Ds-t. The absorption coefficient, refractive index, loss factor (loss tangent), extinction coefficient and optical conductivity were affected by Ds-t variation.

Electronic, Optical, Thermoelectric and Elastic Properties of RbxCs1-xPbBr3 Perovskite.

Inorganic halide perovskites of the type AMX3, where A is an inorganic cation, M is a metal cation, and X is a halide anion, have attracted attention for optoelectronics applications due to their better optical and electronic properties, and stability, under a moist and elevated temperature environment. In this contribution, the electronic, optical, thermoelectric, and elastic properties of cesium lead bromide, CsPbBr3, and Rb-doped CsPbBr3, were evaluated using the density functional theory (DFT). The generalized gradient approximation (GGA) in the scheme of Perdew, Burke, and Ernzerhof (PBE) was employed for the exchange-correlation potential. The calculated value of the lattice parameter is in agreement with the available experimental and theoretical results. According to the electronic property results, as the doping content increases, so does the energy bandgap, which decreases after doping 0.75. These compounds undergo a direct band gap and present an energies gap values of about 1.70 eV (x = 0), 3.76 eV (x = 0.75), and 1.71 eV (x = 1). The optical properties, such as the real and imaginary parts of the dielectric function, the absorption coefficient, optical conductivity, refractive index, and extinction coefficient, were studied. The thermoelectric results show that after raising the temperature to 800 K, the thermal and electrical conductivities of the compound RbxCs1-xPbBr3 increases (x = 0, 0.25, 0.50 and 1). Rb0.75Cs0.25PbBr3 (x = 0.75), which has a large band gap, can work well for applications in the ultraviolet region of the spectrum, such as UV detectors, are potential candidates for solar cells; whereas, CsPbBr3 (x = 0) and RbPbBr3 (x = 1), have a narrow and direct band gap and outstanding absorption power in the visible ultraviolet energy range.

Optical Properties of GaAs Nanoparticles in Acetone by Laser Ablation

Gallium arsenide (GaAs) nanoparticles' optical and emission properties can be tuned bychanging their size across the visible spectrum. GaAs nanoparticles' optical characteristics aredegraded by oxidation on their surface. This work investigated the optical constants and the opticalband gap for a GaAs nanoparticle immersed in acetone using the laser ablation into liquids (LAL)technique after being exposed to a Nd: YAG pulsed laser operating at the wavelength (1064nm)10Hz frequency, and 7ns pulse width for a fixed flounce of 1.32 J/cm2, and the time of ablationwas 5 minutes. In order to calculate the optical conductivity (σ), refractive index (n), extinctioncoefficient (k), dielectric constant, absorption coefficient (α), and optical band gap, an opticalinvestigation was carried out utilizing a UV-Visible Spectrophotometer region in the wavelengthrange 300-1200 nm. The band gap energy was determined to be 3.8 eV, which is greater than thebulk Ga energy. The band gap energy of nanoparticles increases with increasing laser pulse energyand decreases with increasing pulse repetition rate. Transmission spectra increased as wavelengthsincreased, while optical absorption coefficients, extinction coefficients, and refractive coefficientsdecreased. The difference in optical constants is explained by defect states and the average bandenergy of the system. The acetone stability test reveals a peak at -0.69 mV, indicating low stabilityin nanoparticles.

An improved method to determine the minimum extinguishing concentrations of ultrafine dry powder agents: Taking NaHCO3 and KHCO3 as examples

Ultrafine dry powder agents (UDPAs) are the most potential Halon substitutes due to the high extinguishing effectiveness and excellent environmental friendliness. Nevertheless, the method for obtaining minimum extinguishing concentration (MEC) is flawed and inaccurate. An improved method is proposed by developing the special laser measurement system without powder contamination, the concentration calibration test bench and the cup burner with uniform aerosol generating. The results show that the optimum calibration position is 0.35–0.65 m from the inlet in the y-axis coordinate. More accurate mathematical relationships between the transmittance of the laser measurement system and the NaHCO3 and KHCO3 powders are established, with the errors less than 12%. Upon reaching MECs in the modified cup burner, the flames pulsate, then fade and eventually die. Based on the phenomenon of the sudden change in the transmittance of the laser measurement system at the moment of flame extinguishment, i.e. the “step shape” curve, a more accurate critical criterion point for the MEC is proposed. The measured MECs for methane flames by NaHCO3 (32.2 g/m3) are approximately 4 times that of KHCO3 (8.2 g/m3), consistent with previous studies. The obtained MECs of NaHCO3 and KHCO3 for kerosene flame are verified by 1 m3 total flooding fire extinguishing experiments. The improved method may guide the design of industry fire protection systems based on UDPAs to achieve process safety.

In this paper, the structural and optical properties of pure Tin Oxide and doped by Fluorine (F). Thin films were studied prepared by chemical spray pyrolysis on glass substrates at temperature 400oC. The nature of crystallization of the compounds was examined by using X-Ray diffraction technique which showed that the prepared thin films are polycrystalline structure, and the doping processes didn,t show any obvious differences on the crystalline structure of (SnO2). The DC conductivity measurements of the samples were performed by means of a two probe method. The activation energies were computed from the plots of σdc versus 1000/T. To obtain the optical parameters, the absorption and transmittance spectra were recorded in the wave length range 300-1100 nm, the energy gap of the direct and indirect allowed transition were calculated. The optical parameters such as absorption coefficient (α), refractive index (n), extinction coefficient (Ko), dielectric constant (ε'), and dielectric loss (tanδ), were also investigated.

Structural and optical properties of Sb–BaTiO3 and Y– BaTiO3 doped ceramics prepared by solid-state reaction

Barium titanate ceramics synthesized employing the solid-state method were investigated for their optical properties and phase transition characteristics. X-ray diffraction method and Scanning electronic microscopy were used to reveal a typical perovskite structure. The average grain size of (Sb or Y) doped barium titanate ceramics falls considerably as the concentration of Sb2O3 or Y2O3 increases. XRD investigation revealed the creation of cubic crystal structure. The impact of (Sb, Y) concentration on structure, including the appearance of various tetragonal phases, grain size reduction, and microstructure development, was investigated. The cell parameters of the formed phases decrease from 4.05418 to 3.99385 and from 4.05418 to 3.98605 as the doping rate increases Ba1-x SbxTiO3 and Ba1-xYxTiO3 ceramics respectively,where (x = 0.00,x = 0.05, x = 0.1, x = 0.15 and x = 0.20).Crystallites sizes of Sb-doped BaTiO3 crystals changes from 34.59 to 40.47 nm when dopant concentration is changed from 0.05 to 0.20. For Y doped BaTiO3 crystallite change in size from 28.92 to 29.10 nm. Additionally, assessed were the absorption coefficient (α), extinction coefficient (k), and refractive index (n). When the concentration of Sb3+ or Y3+ ions is increased from 0.05 to 20%, the values of the energy bandgaps for Ba1-x SbxTiO3 and Ba1-xYxTiO3 increase from 3.11 to 3.17 eV and 3.07–3.14 eV, respectively. It is found that the refractive index(n) rises as wavelength rises. It has been shown that the absorption coefficient (α) increases when photon energy increases. It is found that the extinction coefficient (k) decreases with wavelength. The extinction coefficient (k) and the absorption coefficient (α) are both observed to decrease with increasing concentration for all compositions.

Polarization-Dependent Absorption and Transmission Metasurfaces for Linearly and Circularly Polarized Light in Terahertz Band

Polarization detection is an important part of many polarization applications such as polarization imaging, wireless communication, and circular dichroism spectroscopy. In this paper, two polarization-dependent terahertz wave absorption and transmission metasurface for linearly and circularly polarized light are proposed and proved by numerical simulations. Polarization filtering and polarization absorption are integrated on a single cell, and the orthogonal polarization component is transmitted and absorbed, respectively. The linearly polarization-dependent transmission and absorption structure can obtain a transmission extinction ratio of 11.5 dB and an absorption extinction ratio of over 270 dB at 3 THz. Moreover, the circularly polarization-dependent structure can obtain a transmission extinction ratio of 8.1 dB and an absorption extinction ratio of 4.66 dB at 2.8 THz. Our design facilitates the acquisition of full Stokes parameters and the high-resolution imaging.

Electronic and optical properties of the R3 Ni3TeO6 compound described by the modified Becke-Johnson exchange potential

Calculations based on the density functional theory (DFT) have been realized to study the electronic and optical properties of the Ni3TeO6 compound with a hexagonal crystal structure (R3 space group). Exchange and correlation electronic effects were described by a modified Becke-Johnson (mBJ) potential in its semiconductor variance form. The collinear antiferromagnetic state of the R3 Ni3TeO6 compound was simulated. The calculated spin magnetic moment of the Ni atoms (1.65 μB) was found to be in good agreement with the experimental result (2.03 μB). Moreover, the calculated optical band gap (2.8 eV) agreed well with the experimental prediction (2.5 eV). These facts suggest a reliable electronic structure description of the material. Hence, we also calculated the complex dielectric function, optical absorption spectrum, refractive index, and extinction coefficient. The optical absorption spectrum was interpreted based on the determined electronic structure. The direct optical absorption edge of the material was characterized by the electronic transitions from O 2p states to Te 5s states and from Ni 3d states to O 2p states. This description did not agree with previous ones based on DFT + U calculations or those made based on the electronic structure of the Ni3V2O8 compound. Thus, an alternative description of the electronic structure of the R3 Ni3TeO6 compound in its antiferromagnetic state using the DFT + mBJ calculations has been suggested, and consequently a new origin for the optical absorption observed around the optical band gap.

Comparative Study on Structural and Optical Properties of Se85Te6Bi9 Nano-Thin Films Synthesized at Disparate Ambient Argon Pressures

In this research work, we have synthesized amorphous Se85Te6Bi9 Chalcogenide Glasses (ChGs) using Melt Quenching Technique. The glassy nature of the synthesized specimen was confirmed by the DSC thermogram plotted at the heating rate of 20 K/min. The nano-thin films of such synthesized samples at two disparate working pressures (1 torr and 3 torr) of ambient argon gas were made using the Physical Vapour Condensation Technique on the ultrasonically cleaned glass substrates. During the synthesis process of nano-thin films substrate temperature (77 K) was kept constant using liquid nitrogen and the thickness of prepared thin films was 40 nm. The morphological analysis of the prepared nanochalcogenide thin films using FESEM confirmed the nanochalcogenide particle size ranges from 20–80 nm. More aggregation and reduction in particle size on the substrates were observed with an increase in working pressure for Se85Te6Bi9 nano-thin films. HRXRD pattern confirmed the amorphous nature of the synthesized nano-thin films. Based on UV-Visible spectroscopy, the optical parameters such as optical absorption coefficients, optical direct band gaps and extinction coefficients were measured for synthesized Se85Te6Bi9 nanochalcogenide thin films. The value of absorption coefficients and extinction coefficients increases with the increase of ambient argon pressure, whereas the value of the optical direct band gap increases with increasing working pressure due to the quantum size effect and dominance of coulombic interactions. The estimated value of optical direct band gaps are 1.37 eV and 1.47 eV at 1 Torr and 3 Torr respectively making our synthesized nano-thin films a preeminent candidate for solar cell applications and other photonic devices.

The energetic and physical concept of gold nanorod-dependent fluorescence in cancer treatment and development of new photonic compounds|review.

The optical features of gold nanorods (GNR) may be precisely controlled by manipulating their size, shape, and aspect ratio. This review explores the impact of these parameters on the optical tuning of (GNR). By altering the experimental conditions, like the addition of silver ions during the seed-mediated growth process, the aspect ratio of (GNR) may be regulated. The shape is trans from spherical to rod-like structures resulting in noticeable changes in the nanoparticles surface plasmons resonance (SPR) bands. The longitudinal SPR band, associated with electron oscillations along the long axis, exhibits a pronounced red shift into the (NIR) region as the aspect ratio increases. In contrast, the transverse SPR band remains relate unchanged. Using computational methods like the discrete dipole approximation (DDA) allows for analyzing absorption, scattering, and total extinction features of gold (G) nanoparticles. Studies have shown that increasing the aspect ratio enhances the scattering efficiency, indicating a higher scattering quantum yield (QY). These findings highlight the importance of size, shape, and aspect ratio in controlling the optical features of (GNR) providing valuable insights for various uses in nanophotonics and plasmonic-dependent fluorescence in cancer treatment and developing new photonic compound NRs.

THE EFFECT OF 0.1 WT% IODINE ADDITION ON THE OPTICAL PROPERTIES OF POLYETHYLENE OXIDE FILMS

The study aimed to investigate the optical properties of thin films made of polyethylene oxide dispersed with dopants of a fixed amount of iodine (0.1 wt %). The films prepared by the casting method were optically investigated as a function of the iodine fillers. The study used a UV-visible spectrophotometer technique with a wavelength ranging from (200 to 800) nm and determined the absorption coefficient, refractive index, energy gap, extinction coefficient, optical conductivity, and dielectric constant in the UV-visible wavelength range. The results showed a noticeable change in these optical values with polyethylene oxide doped with 0.1 wt% iodine composites compared with the pure polyethylene oxide films. These measured values of polyethylene oxide doped with 0.1 wt% iodine depend on the wavelength of the incident ultraviolet light.

Experimental study of flame extinguishing of red pine wood pyrolysis gas by NH4H2PO4 powder based on Cup-burner

Suppression of forest fires has been one of the important research directions in the field of fire safety, ammonium phosphate and its mixture of inhibitors commonly used in solid combustible fires, for forest fire scenarios, also has a good fire suppression effectiveness, inexpensive and easy to store, but also the current suppression of forest fires is one of the main inhibitors. However, there are few studies on the interaction between ammonium phosphate and forest fires. In this paper, to facilitate the study, we enter the previous research ideas for gas fires, reduce the scale of the research object, establish a small-sized simplified flame model for suppressing wood fires, take red pine wood as the research object, analyze the pyrolysis gas components after high-temperature pyrolysis, and construct the Cup-burner experimental system, together with an improved powder delivery control system, so that the process of NH4H2PO4 powder quenching fuel flames such as red pine pyrolysis gas at 350 °C, 450 °C and 550 °C was well presented on this device. It was found that the flame morphology was not only related to the gas composition but also the amount of NH4H2PO4 powder added and the particle size; the Minimum fire extinguishing concentration(MEC) value was not only related to the gas composition but also the particle size of NH4H2PO4 powder. This is because the CO2 content decreases and the H2 and CH4 content increase significantly in the gas composition at 550 °C compared to the 450 °C gas composition. Among the same pyrolysis gas components, the MEC value gradually increased as the particle size of NH4H2PO4 powder decreased, and the MEC value of 30 μm–40μm particle size powder was the lowest, and the difference between the particle size MEC value and the other two particle sizes was large, while the difference between the MEC values of 20 μm–30μm particle size powder and 10 μm–20μm particle size powder was small; according to the Cup-burner test The chemical thermodynamic analysis was carried out according to the results of the Cup-burner test to obtain the proportion of NH4H2PO4 powders playing a physical role in fire extinguishing. When NH4H2PO4 powder is involved in syngas/air combustion, the end product is P2O5 and xsp = 2.35%. When the end product is HPO3, xsp = 7.29%. The products were collected after the interaction of NH4H2PO4 powder with the synthesis gas flame, and the analysis of the products revealed that the products were sticky and not dry solids, and the material analysis of them revealed that they contained more HPO3 and its mixture, which shows that the physical heat absorption played a greater role when NH4H2PO4 powder interacted with the synthesis gas flame.

Combustion inhibition of cup-burner flame with C2HF3Cl2 and its kinetics mechanism investigation

Fire extinguishing performance and mechanism of C2HF3Cl2 (R123) were studied by experimental and theoretical methods. The minimum extinguishing concentration (MEC) of R123 in methane/air flames is 7.31 %. The addition of R123 to flame increased first and then decreased the flame height, due to the effect of R123 on the movement of the reaction kernel. Theoretical calculations indicated that R123 and pyrolysis products affect the combustion reaction, the generated fluorine or chlorine-containing groups improved the suppression of combustion chain reactions. The in-depth experimental and theoretical study of R123 boost the development of ideal halon replacement in aircraft cargo compartment.

Tunable band gap, CB and VB positions of multicomponent Se65-xTe20Ge15Snx chalcogenide glassy systems: Effect of metallic additives on physical and optical parameters

In the present communication, the compositional dependency on physical, and optical properties of chalcogenide Se65-xTe20Ge15Snx (x = 5, 10, 15, and 20 at. wt. %) glassy systems have been studied. A comprehensive evaluation of various physical and optical parameters has been analyzed systematically. The spectroscopic parameters have been determined from the transmittance and reflectance spectra using spectrophotometric measurements in the range of 200 nm–1200 nm. The optical energy band gap of the as-prepared samples has been evaluated by deploying Tauc's plot method and is observed to decrease from 1.28 eV to 0.93 eV, while the calculated Urbach energy is observed to increase from 0.110 eV to 0.208 eV with the increasing content of the metallic additives. By using the Wemple-Di Domenico model, the dispersion parameters of the samples are obtained and discussed comprehensively. An increase in Sn content is found to affect the absorption coefficient, extinction coefficient, refractive index, optical density, skin depth, and optical conductivity of the glassy systems. By using the chemical bond approach the estimated cohesive energy values are found to increase from 45.39 kcal/mol to 46.75 kcal/mol. Moreover, the location of conduction and valence band edge has been estimated to examine the potential of the synthesized samples as a semiconductor device. The analyzed properties make the multicomponent Se–Te-Ge-Sn chalcogenide system, a potential candidate for numerous device applications.
