Enhancement of CdO Film Via Li Additive: Structural and Optical Properties

Abstract

Chemical spraypyrolysis technique was used to prepare  thin film of pure nanostructured CdO and nanostructured Li-doped CdO with volumetric concentration of (1 and 3.%). By using XRD, the prepared films on glass substrate have been studied  and found to be cubic structure.Through the use of  UV-Visible spectrophotometer we have determined the optical parameters like transmittance and optical constants. The optical energy gap of CdO was decreased from 3.92 eV for pure CdO film to 3.8 eV for the CdO:3%Li film.
