CdO thin films have been deposited onto glass substrate by chemical spray pyrolysis.Transmittance and reflectance spectra in the range300-900 nm were recorded via UV-Visible spectrophotometer for various In-content in the CdO:In thin films.Transmittance decreased with increasingIn-content in the CdO:In thin films, while thereflectance slightly increased in the wavelength more than 480 nm. Urbach energydecreased with increasing In-content in the CdO:In thin films. Dispersion parameters arecalculated, and find that E d , E o , e ∞ , n(0), S o ,M -1 and M -3 are increased with increasing In-content in the CdO:In thin films. more...
