Effect of Molara Concentration on Structural, Morphological and Optical Properties of CdO Thin Films Prepared by Chemical Spray Pyrolysis Methode

Nadia Jasim Ghdeeb

Abstract: Structural, Morphological and optical properties of CdO thin film were presented in this work. The Cadimium Oxide (CdO) semiconducting films are deposited on glass substrate by chemical spray pyrolysis methode. The crystalline structure was studied by X-ray diffraction (XRD) having found the presence of the CdO cubic phase. The AtomicForce Microscopy (AFM) micrographs prove that the grains are uniformly distributed within the scanning areas (2053.41 nm 2065.63 nm). All samples show an abrupt changein transmission which indicates a direct transition and good crystallinity. Optical absorption measurements showed that films has high absorption coefficient in the UV region, whereas it is transparent in the visible region for CdO film, and it is decreasing and shifted toward the visible region for molarea concentration increas. The direct band gap energy was determined and found to be in the range 2.6 2 eV.
