Synthesis and Characterization of 〖(CdO)〗_(1-x) 〖Mg〗_x films by pulsed laser deposition

Abstract

In this study, the effect of grafting with magnesium (Mg) ratios (0.1, 0.3, 0.5) on the structural and optical properties of cadmium oxide films (CdO) was studied, as these films were prepared on glass bases using the method of pulse laser deposition (PLD). The crystallization nature of the prepared films was examined by X-ray diffraction technique (XRD), which showed that the synthesis of the prepared films is polycrystalline, and (AFM) images also showed that the increased vaccination with magnesium led to an increase in the grain size ratio and a decrease in surface roughness, The absorption coefficient was calculated and the optical energy gap for the prepared thin films .It was found the absorption increases and the energy gap decreases with the increase of doping ratio.
