Cadmium oxide in thin film was deposited on glass substrates by spray pyrolysis technique
from aqueous solution of cadmium nitrate. The diagrams of X-ray diffraction show that the
films are polycrystalline. Morphological study shows uniform deposited film and submicron
sized grains growth perpendicularly on substrate surface. Optical gap energy of cadmium
oxide was estimated to be 2.15eV. Optical study shows that CdO film transmitted in visible
and in the near red infrared wavelength range. The conductivity study indicates a semiconducting
behavior of cadmium oxide in thin films. Dielectric response of cadmium oxide
films was interpreted by orientation and space charge polarization.
