This study presents the synthesis of a novel ovonic nanomaterial by the chemical route approach, involving the combination of three distinct materials: polyvinyl alcohol (PVA), iron oxide (Fe2O3), and selenium (Se) nanoparticles. The produced material underwent evaluation using various analytical techniques, including Xray diffraction (XRD), energy- dispersive Xray spectroscopy (EDS), scaning electron microscope (SEM), and UV-Visible spectrophotometer. The focus of the work revolved around a unique hybrid structure consisting of selenium nanoparticles that were embedded within a polyvinyl alcohol and iron(III) oxide. The examination of micro structure information yielded findings that support the notion that Se nanoparticles have an impact on the structural properties of PVA/Fe2O3. (XRD) and (EDS) examines provided confirmation of the formation of a novel composite structure. The produced composites had notable absorption peaks at a wavelength of 530 nm for PVA-Fe2O3-CdZnS. These composites exhibited a progressive transition towards absorption in higher wavelength areas. The composite material that has been suggested for potential utilization in forthcoming energy storage applications.
