Effect of gamma irradiation on the structural, optical, and electronic properties of PVC/BiVO4/ZnO nanocomposite films
This study investigates the impact of gamma irradiation on the structural, optical, and electronic properties of PVC/BiVO4/ZnO nanocomposite films. Gamma irradiation induced significant modifications, including a decrease in BiVO4 crystallinity, a redshift in the optical bandgap, and a decrease in photoluminescence intensity. These changes suggest alterations in the electronic structure and charge carrier dynamics within the nanocomposite. While gamma irradiation led to a decrease in crystallinity, the observed bandgap reduction could potentially be exploited to enhance photocatalytic activity by allowing the absorption of a wider range of visible light. Further research is warranted to optimize irradiation conditions and investigate the photocatalytic performance of the irradiated films. These findings provide valuable insights into the potential of gamma irradiation as a tool for tailoring the properties of PVC/BiVO4/ZnO nanocomposites for various applications, including photocatalysis, sensors, and optoelectronic devices.
