Summary:In this work, the casting method was utilized to prepare thin poly(vinyl alcohol) films with silver oxide (Ag2O) and zinc oxide (ZnO) nanoparticles with different percentage weights (1%, 2%, and 3%) were produced in this study. Were created Physical attributes such as X-ray diffraction (XRD) do not include structural features. The XRD measurements showed both the hexagonal crystalline structure of ZnO, the simple cubic structure of Ag2O and the amorphous structure of PVA film. UV-visible spectroscopy was used to examine the effects of ZnONPS and Ag2ONPS on PVA's optical characteristics, including absorption, transmission spectrum, absorption coefficient, extinction coefficient, and energy gap. The experimental results of the optical properties of PVA: Ag2O-ZnO nanocomposites showed that the absorption, absorption coefficient, refractive index, of dielectric constant and optical conductivity of PVA mixture increased with increasing concentrations of Ag2O and ZnONPs, while the transmittance and energy gap decrease with increasing concentration of Ag2O and ZnONPs. This work demonstrates how an increase in Ag2O and ZnONPs affects each of these variables.
