Title: Synthesis and Characterization of Ni and Cu Doped Zno
Abstract: In this work pure and transition elements (Ni & Cu) doped Zinc Oxide is prepared.All the samples were prepared through chemical co-precipitation method, by using sulfates of metallic precursors.We have doped pure ZnO with Ni and Cu by 3% by weight concentration.Further the structural, Crystallite size and band gap approximation studies were performed by utilizing X-ray diffraction and spectroscopic techniques respectively.X-ray diffraction (XRD) result indicates that the sample possess a crystalline wurtzite single phase.Crystallite size is in 19-30nm range.PL characterization gives optical band gap that is 2.65eV-3.02eV.FTIR gives the molecular band present in the samples.UV-Vis shows red shift in peak wavelength.
