Summary: The main objective of this work was to experimentally confirm the formation of a continuous, substitutional solid solution in the pseudo-binary system YVO4-YbVO4 and investigate its unknown properties as a function of composition. The results show that the solid solution has a structure composed of YVO4 and YbVO4, and its crystalline lattice contracts and energy gap decreases with an increase in the parameter (x). The solid solution is stable in the air atmosphere up to approximately 1500 degrees C and belongs to the semiconductor category.

Summary: This research article focuses on the synthesis and characterization of Na(1_ x)Zr2Smx(PO4)(3) (x = 0.005-0.05) phosphors. The phase purity, lattice parameters, chemical states, and morphology of the synthesized phosphors were thoroughly investigated. The study identified a strong characteristic emission from Sm3+ ions and extensively explored the effect of doping concentration on the photoluminescence spectra. The bandgap of the phosphors was measured and found to be in the range of 4.25 - 4.56 eV.

Summary: This article reports the successful synthesis of high-purity NaZr2(PO4):Eu3+ phosphate phosphor by solution combustion synthesis which emits in the reddish region. The structural, vibrational, elemental composition, electronic, and optical characteristics of the synthesized phosphor were analyzed using various measurements. The phosphor showed emission in the visible area due to the magnetic dipole transition of the Eu3+ ions, and it exhibited a high color purity of 94% in the reddish region. These findings suggest that the phosphor could be suitable for various optoelectronic devices, including phosphor-converted whitelight-emitting diodes.

Summary: The structural, optical, and surface properties of indium tin oxide (ITO) thin films deposited by RF magnetron sputtering were investigated in this study. It was found that deposition time affects the crystalline size, surface roughness, optical transmittance, band gap, and refractive index of the ITO thin films. The thickness, elemental concentration, and controllability of the ITO thin films were also discussed in relation to deposition time.

Summary: This study investigates the physical and radiation shielding capabilities of a newly developed glass system incorporating silica extracted from rice straw ash. The purity and chemical composition of the silica are determined, and the synthesized glass is confirmed to be amorphous. Various parameters, including molar volume, optical parameters, and density, are investigated. Experimental measurements of gamma-ray shielding parameters are conducted, and the results are compared with theoretical calculations. The newly prepared glass system is found to have superior properties for shielding gamma-rays compared to other common materials.

Summary: Swift heavy ion irradiation is a powerful method for creating nanostructures on thin films' surfaces. The localized rise in temperature and rapid energy dissipation lead to the formation of disordered or amorphous ion tracks. Increasing ion fluence and overlapping of these tracks result in surface instabilities and the formation of nanostructures.

Summary: CeO2 nanoparticles were synthesized using a simple chemical method without surfactants or additives at low temperature and short reaction time. The effect of annealing temperatures on the structural, morphological, and chemiresistive properties of the CeO2 nanoparticles was investigated. The CeO2 nanoparticles exhibited a cubic crystal structure and porous morphology, with a specific surface area of 52.92 m2/g. The optimized operating temperature was found to be 150 degrees C, showing excellent response and stability towards NO2 gas.

Summary: A simplistic method was used to synthesize NaSr(1-x)VO4:xMn(2+) nanophosphors with 0.25 <= x <= 3.0 mol% through combustion synthesis route, using urea as an organic fuel. The structural, spectral, and optical properties were examined, revealing the mid gap absorption phenomenon when doping the host with Mn2+ ions. Photoluminescence analysis showed two prominent emissions at 434 nm and 523 nm under excitation at 380 nm, indicating the potential of this phosphor material to be excited by UVA emitting InGaN LEDs.

Summary: Solvothermally synthesized zirconium oxide nanopowders, pure and doped with different amounts of iron ions, were used to modify glassy carbon electrodes for the electrochemical oxidation of 2,4,6-trichlorophenol. The results showed that iron doping enhanced the activity of zirconia matrix towards TCP electrooxidation, with different iron contents affecting the oxidation pathway of TCP. The formation of polyphenol film on the electrode surface was more pronounced with higher iron ion content.
