Abstract:   (1457 Views)
In this study, ZnO and nickel doped zinc oxide nanoparticles were prepared by sol-gel method. The optical properties of these nanoparticles were studied by uv-visible spectroscopy. In this way, absorption and transmission features of ZnO were studied as a function of increasing nickel amounts. According to the results, doping zinc oxide with nickel decreases its band gap but by increasing the percentage of nickel enhances the band gap drastically. The size and morphology of the synthesized nanoparticles was evaluated by scanning electron microscopy. Photocatalytic activity of the samples was also investigated.
Keywords: Nickel doped ZnO, -sol-gel, UV-visible Spectroscopy, photocatalytic activity
