Summary: Ti and Si doped ZnO thin films were fabricated using the sol-gel spin coating method. The structural and optical properties of the films were investigated using various characterization techniques. The results showed that the surface morphology consisted of ZnO fiber structures and the thickness of the films increased with Ti content. XRD and Raman spectra confirmed the retention of the hexagonal wurtzite crystal structure, while the crystallinity decreased. The films exhibited high optical transmittance and a redshift in the UV spectrum with increasing Si concentration.

Summary: The structure and magnetization of polycrystalline Zn1-xMnxO3 films (0 <= x <= 0.1) grown on glass and Si substrates using Sol-Gel technique have been studied. It has been found that films grown on Si substrates exhibit ferromagnetic properties after thermal annealing while films grown on glass substrates did not exhibit ferromagnetic order even after thermal treatment. This suggests a potential procedure for achieving room temperature ferromagnetism in Mn doped ZnO films on p-type Si substrates for spintronic device applications.

Summary: The influence of Y2O3 dopant on the optical and mechanical properties of ZrO2 thin films was studied. The microstructural characterization and analysis showed that the films crystallize in the cubic phase, regardless of dopant content. Additionally, it was observed that the refractive index increases while the optical absorption and extinction coefficients, hardness, and elastic modulus decrease with increasing Y2O3 dopant.

Summary: Mesoporous thin films are widely used for their high surface area and efficient mass and charge transport properties. A two-step calcination process can reduce film contraction and enhance structural control, resulting in mesoporous films with higher porosity and larger pores. These films exhibit favorable characteristics for mass transport of large molecules.

Summary: In this study, stable 12Ce-ZrO2 nanoparticles were successfully prepared using a novel sol-gel-flux method, and were compared with the product synthesized using the traditional sol-gel method. The results showed that the sol-gel-flux method exhibited better sintering ability and more homogeneous microstructure.

Summary: The authors present an innovative and rapid process for producing ZrN thin films using a photo-structurable ZrO2 sol-gel and a rapid thermal nitridation (RTN) process. Compared to traditional methods, the sol-gel method allows for the production of ZrN thin films on non-planar and large substrates in a shorter time and at a lower cost. The produced ZrN films were characterized and their optical, electrical, and tribological properties were investigated.

Summary: The effect of Co doping concentration on the structural, morphological, optical and electrical properties of NiO thin films was investigated. The doped films showed polycrystalline structure with a preferential orientation in (111) direction, uniform surface morphology with spherical shaped nanocrystalline grains, high transmittance in visible and NIR regions, reduced band gap value, improved conductivity and high figure of merit values. These findings suggest the potential applications of Co-doped NiO films in optoelectronic devices.

Summary: This study focuses on fabricating VO2 films doped with different contents of tungsten (W) element on high-purity Si substrate. The films exhibited good crystallinity and uniform thickness. X-ray diffraction and X-ray photoelectron spectroscopy characterizations showed that W can be doped into the VO2 lattice, resulting in small lattice distortion. In situ FT-IR measurements revealed that the phase transition temperature of the films can be continuously decreased with increasing W doping content. The doping also significantly enhanced the film's conductivity and reduced optical transmittance. These findings provide important insights into designing doped VO2 films for silicon-based devices.

Summary: Aluminum and rubidium-doped zinc oxide thin films were deposited on glass substrates using sol-gel dip coating method. The effect of dopant content on structural, surface morphological, vibrational, and optical properties was studied using X-ray diffraction, SEM-AFM, and Raman spectrometer. It was observed that introducing Rb impurities into the ZnO lattice resulted in a deterioration in crystal quality and a blue shift in the bandgap. The increase in dopant concentration led to a change from hydrophilic to hydrophobic nature and showed significant antibacterial activity against E. coli.

Summary: Thin films of un-doped and cerium-doped zinc sulfide with various doping concentrations were prepared and studied for their structural, morphological, optical, and photoluminescence properties. The results showed that doping concentration affected the surface morphology and visible transmittance of the films, while UV-visible spectroscopy and room temperature PL spectroscopy revealed different emission characteristics.
