As a promising nanostructure to use in various optoelectronic nanodevices, PVA–ZrO2–CuO nanocomposites (NCs) are created in this study using the casting method with different ratios of ZrO2/CuO. Compared to other nanosystems, the PVA–ZrO2–CuO nanostructures stand out for their low cost, high corrosion resistance, good optical properties, and lightweight. The investigation is focused on examining the structural and optical characteristics of nanocomposites composed of PVA–ZrO2–CuO. FTIR spectra indicate a physical interference between the pure polymer and nanoparticles. The optical microscope is used to describe the structural properties and the changes in the surface morphology of nanocomposite. The findings about the optical characteristics indicate an increase in absorption by approximately 283%. Additionally, the energy gap experiences a decrease by approximately 107% for allowed indirect transitions and 408% for forbidden indirect transitions. These changes are observed, when the PVA–ZrO2–CuO content reaches a weight percentage of 6%. Consequently, these results suggest that the material may possess suitability for a range of optoelectronic devices. [ABSTRACT FROM AUTHOR] |
