Abstract

This study examined the properties of polyvinyl alcohol (PVA) as a matrix composite, specifically focusing on the characterization techniques of UV-Visible spectroscopy, X-ray diffraction (XRD), and scanning electron microscopy (SEM) with energy dispersive spectroscopy (EDX). The investigation centered around a novel hybrid structure composed of CdZnS nanoparticles implanted within a composite matrix of PVA and Fe₂O₃. The analysis of microstructure data provided evidence of the influence of CdZnS nanoparticles on the structural characteristics of PVA–Fe₂O₃. The composites that were synthesized exhibited significant absorption peaks at wavelengths of 233 nm and 234 nm for PVA-Fe₂O₃ and PVA-Fe₂O₃-CdZnS, respectively. A progressive shift towards higher wavelength regions of absorption was found in these composites. The X-ray diffraction (XRD) analysis revealed an average crystalline grain size of 38.417 nm for Fe₂O₃ and 27.267 nm for PVA-Fe₂O₃-CdZnS.
