| Abstract | ||
| This research deals with the Preparation of pure and lithium doped CdS Thin Films by chemical bath deposition method , thickness (450±20)nm and the Preparation temperature (75ᵒC) . The results of XRD showed that the films had a polycrystalline hexagonal structure . The preferred orientation was along (002) plane. The average crystallite size Increasing with increasing The doping . The results of the ( AFM ) showed that the roughness and (RMS) value were increased with doping . Results (SEM) showed that the films were uniformly distributed and homogenous . The optical properties were studied by recording the Absorption and Transmittance spectra of the wavelength range from (300-1100)nm, It was found that Absorption increased and Transmittance decreased with increasing doping . It was also found that the Absorption Coefficient increased with increasing doping , Optical Energy Gap found decreased with increasing doping from (2.72 – 2.89 )eV. | ||
