Structural and optical properties of CdxZn1-xO Thin Film Prepared by Chemical Bath Deposition Method

Abstract

In the present work, CdxZn1−xO thin film with different Cd volume ratios in solution (x=0, 0.3, 0.5,0.7, and 1) have been deposited on glass substrate by chemical bath deposition method. The prepared films were characterized by using X-ray diffraction and UV–Vis spectroscopy measurements. The results show that the samples are polycrystalline and the crystallinity of the films enhanced with the increase of x value .The average transmittance of CdxZn1-xO films in the visible region was between (70–81%) with direct optical energy decreases from(3.34eV) to(2.38eV) when the value of x increases.
