| Popis: | Different types of copper oxides doped zinc oxide thin films have been prepared onto glass and silicon substrates by spin coating process with different concentration of Cu (0, 1 and 3) wt%, XRD analysis revealed the films were polycrystalline as well as the incorporation of Cu+1 and Cu+2 cations in ZnO matrix; surface morphology and topography have been measured by AFM indicated the roughness and average grain size increased with copper concentration, UV–Vis spectroscopy measurements were performed to evaluate transmittance and found to be (>80%) in the visible region while energy gap decreased with copper concentration, empirical equation has been formulated to predict the energy gap as a function of copper concentration and crystallite size coincident perfectly with the experimental data. |
