Effects on Structural, Functional groups and Photo Luminance Properties of Copper Doped Zinc Oxide Nanoparticles

Abstract

Present study we reported the structural, optical and functional group study of copper-doped zinc oxide nanoparticles (NPs) synthesized by chemical co-precipitation method. In this study doping concentration of copper (0.2, 0.4, 0.6) was incorporated in zinc oxide. All the synthesized samples were characterized by X-ray diffraction (XRD) as well as Fourier transform infrared (FTIR) and studied the photo luminance (PL) property. XRD study confirms the structural and purity of ZnO and Cu doped ZnO nanoparticles. The average grain size of pure ZnO was calculated by Scherrer formula and it varied according to doping concentration from 25.10 to 20.26 nm. The average grain size of pure ZnO was decreased for Cu-doped samples. The presence of functional groups and chemical bonding were confirmed by FTIR. Due to the doping concentration of copper the structural, functional group and photo luminance properties of ZnO was changed drastically.
