Synthesis of nickel doped Zinc Oxide via solid state reaction method

Nickel doped Zinc Oxide, Zn1-xNixO, (x= 0.0, 0.1, 0.2, 0.3, 0.4) mole powder have been synthesized by solid state reaction method. Zinc Sulphate Hepthahydrate (ZnSO4.7H2O), Nickel Chloride (NiCl2), sodium hydroxide (NaOH) were mixed together. The optical absorption and microstructure were determined by X-ray diffraction (XRD) and Ultraviolet-visible (UV-Vis) spectroscopy. XRD shows the phase formation of ZnO that was successfully doped with Ni, ZnO gave hexagonal wurtzite structure and Zn0.97Ni0.03O shows the cubic plane structure. The average crystallite size of the Zn1-xNixO are 61.41, 51.95, 53.07, 58.37 and 184.89 nm respectively. UV-Vis Spectroscopy reveal that the effect of ZnO synthesize with Ni is showed the band gap which is decrease from 4.34 eV, 4.31 eV, 4.28 eV, 4.19 eV and 4.15 eV.
