摘要

CdO: NiO films with nano-scale dimensions were deposited on glass substrates at different thicknesses utilized thermal chemical spray pyrolysis technique. The prepare films were characterized with XRD, FE-SEM, and Uv-Vis were employed. XRD analysis confirmed a cubic phase with preferred (111) growth direction. crystalline. FE-SEM studies demonstrated multiple morphologies of nanostructures as semispherical. The optical properties were tested in the range 300–900 nm wavelength, the optical band gap Eg shifted from 2.83 to 2.37 eV, showing a clear correlation with the film thickness.
