Abstract :In this study, we work on the effect of Ni doping on the crystallographic structure, morphology, and optical properties of ZnO nanoparticles. ZnO and Ni doped ZnO nanopowders were synthesized by sol-gel technique with different Ni concentration insert ignore into journalissuearticles values(5%, 10%, and 15%);. The crystallographic structure was characterized by conventional X-ray Diffraction insert ignore into journalissuearticles values(XRD); technique. The results confirm that Ni doping does not change the single hexagonal phase existing in pure ZnO whereas in high Ni doping concentration insert ignore into journalissuearticles values(10% and 15%); causes to grow a secondary phase due to presence of NiO. FE-SEM, EDX, FTIR techniques are used for morphology, elemental, and chemical analyses of the samples. Optical properties of the samples are investigated by using UV-VIS spectrophotometer.
