Abstract

In this work CdO nanocrystalline thin films have been prepared by chemical bath deposition technique(CBD) , on commercial glass substrates at room temperature. cadmium nitrat as a source of cadmium ions(Cd+2) and Ammonium hydroxide as a source of hydroxide ions (OH-2). The effect multiple dip process on the structural and optical properties of CdO films and the use x-ray diffraction(XRD),optical reflection microscope( ORM),and UV-visible spectroscopy respectively(UV) were studied. The results of X-ray diffraction showed  that  conversion of cadmium hydroxide film to cadmium oxide film, the  results  show  of  film  and  increases grain size by increases  the multiple dip process. The optical reflection microscope showed that the films prepared has surface Morphological properties of the thin films and is improved with increased the multiple dip process. The results of optical properties showed that transmittance of film was 74% and decreased with increasing the multiple dip process, and found that the energy gap ranged from 2.24-2.63 eV. and found improved properties films with the multiple dip, This makes them suitable in solar cell applications and the detectors.
