Popis: | ZnO was synthesized by Sol gel method using zinc nitrate as precursor and doped with Cu and Ni. Stress in lattice was evident from the XRD peak shifts. A decrease in crystallite size due to Zener pinning was observed. A variation in absorption intensity based on the defect energy levels was observed. A difference in energy of the emission and absorption spectra resulting from defects in the material and non-radiative decay was seen. A change in band gap was observed with change in different dopant concentrations. |
