Abstract - In this study, pure zinc oxide nanoparticles and nickel-doped zinc oxide nanoparticles were prepared by sol-gel method and graphene quantum dots were prepared by pyrolysis method. Core-Shell structure, ZnO (pure and with nickel impurity)-graphene quantum dots was synthesized. The optical properties of these nanoparticles were studied by photoluminescence spectroscopy. According to the results, the contamination of zinc oxide with nickel element leads to a decrease in the peak intensity of ZnO emissions, but with the addition of quantum dots graphene, the intensity of emission peak increases. In the morphology study, the shape of the synthesized particles was investigated by scanning electron microscopy.
