Abstract
ZnS QDs were synthesized by chemical co precipitation method and then embedded in polyvinyl alcohol (PVA) with different concentrations of ZnS. The samples of ZnS/PVA were characterized by X-ray diffraction (XRD), transmission electron microscopy and Scanning Electron Microscopy. The XRD study showed that the crystallite size was around 9 nm. UV/VIS optical spectroscopy studies were used to determine the energy band gap of ZnS/PVA nanoparticles films against the increase of concentration. The photo stability of QDs ZnS/PVA composites are highlighted. The photo stability rate was enhanced to 48% after 420 min for UV–VIS irradiation. The nanocomposite ZnS/PVA has the optimum properties as a proper candidate for flat panel display, LED and solar collector.
