The structural, morphological and optical properties of CBD deposited CdS thin films have been studied by varying the processing parameters and the Cd/S ratio of the starting precursors in order to better understand the growth conditions. The films were characterized by Xray diffraction, SEM, Raman, and photoluminescence spectroscopy. XRD patterns show that asdeposited CdS films were polycrystalline. The grain size are increasing with increasing the Cd/S ratio and/or the deposition time.
