Study of structural, optical and photoluminescence properties of ZnO doped PVA/PVP nanocomposite

Abstract

We report preparation and characterization of ZnO doped PVA/PVP Polymer nanocomposites using solvent casting technique. The FTIR and XRD studies confirm the formation of polymer nanocomposites through the interaction taking place between the nanoparticles and the polymer. The optical energy gap of the doped polymer decreases with an increase in doping concentration. The photoluminescence studies reveal that the intensity of the peak is maximum for a doping concentration of 8% ZnO. The optical and photoluminescence properties of PVA/PVP blend are enhanced due to doping. This makes ZnO doped PVA/PVP a prominent material for device applications.
