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.
