Summary: The study investigates the optical properties of PVC/ZnO nanocomposite films. The results show that the optical properties of the films are dependent on the concentration of ZnO and the wavelength of light, and the optical parameters can be influenced by altering the concentration of non-annealed and annealed ZnO nanoparticles in the PVC matrix.

Summary: The study reports the impact of thermal annealing on the structural and optical properties of Bi7In28Se65 chalcogenide films, with the 450 degrees C annealed film showing complete crystallinity compared to the less crystalline nature of the 350 degrees C annealed film. Optical analysis showed a decrease in transmittance and an increase in absorbance with annealing, along with a decrease in bandgap and Tauc parameter. The static linear refractive index for the films increased with annealing, indicating the potential for applications in solar cells and nonlinear devices.

Summary: This study aimed to manufacture PVDF/PMMA thin films containing ZnO nanoparticles in different weight ratios by spin coating and use them as high-performance humidity sensors. The films were characterized for their structure, functional groups, transmittance, and optical energy band gap. The results showed that the films had polycrystalline hexagonal structures, with decreasing grain size as the weight ratio of ZnO nanoparticles increased. The films also exhibited a homogeneous distribution of nanoparticles and high sensitivity to humidity. The sensors manufactured using the films had acceptable values for parameters such as response time and retrieval time.

Summary: The effect of different concentrations of zinc oxide on the dielectric properties of composite films was studied. It was found that increasing the zinc oxide content significantly increased the dielectric constant, AC conductivity, and loss tangent. A direct correlation between the dielectric parameter and the mean relaxation time of polymer chain segmental dynamics was observed, suggesting that the dielectric properties of these materials can be tailored by varying the amount of metal oxide filler for use in microelectronics.

Summary: In this study, PVA/ZnO films were irradiated with hydrogen ions at different fluences, and the effects on the structures, morphologies, and functional groups were investigated using XRD, SEM, and FTIR. UV-Vis spectroscopic analysis was also performed to examine the optical properties. The results showed that increasing the number of hydrogen ions led to an increase in the Urbach tail and a decrease in the optical gap. The irradiated PVA/ZnO samples exhibited enhanced structural and optical characteristics, making them suitable for use in optoelectronics.
