Abstract:
The structural properties of CBD deposited CdS thin films have been studied by varying the processing parameters and Cd/S ratio of the starting Precursors in order to better understand the growth conditions. A CdS thin film was prepared on glass substrate by CBD method from a bath containing Thiourea and Ammonium hydroxide. The structural analysis was performed by X-ray Diffraction (XRD). The deposited CdS thin film was a cubic phase with small nano crystalline grains. The film was deposited at 60°C for 2 hours. After sintering the film at 300°C for 1 hour the color of the film was changed like dark yellowish and the thickness of the film was obtained 100 nm. The FTIR was done at room temperature over 350 cm-1 to 4500 cm-1 and it showed the existence of different functional group in the sample and their probable source. These studies have allowed us to establish a standard set of conditions for the fabrication of homogeneous and continuous very thin CdS films in laboratory and this preparation technique is also suitable for preparing highly efficient thin film due to its advantages such as simple, large area films, low deposition temperature and low-cost method.
