Abstract
Pure and doped magnesium oxide (MgO) thin films were prepared with different volumetric ratios (0, 2, 4, 6, and 8%) of zinc sulfide (ZnS) on glass substrates at (350 °C) by chemical spray pyrolysis technique. The surface topography, absorption spectrum, absorption coefficient and Urbach energy of the prepared films were studied. The atomic force microscopy (AFM) results revealed that the surface topography of the prepared films changes as the percentage of doping with zinc sulfide (ZnS) increases. The absorbance spectrometry of the prepared films was measured by UV-vis. The Urbach energy of the prepared thin films increased by increasing the doping ratios with (ZnS).
