Abstract:Electrochemical method was adopted to deposit CdS thin films on the surface of ITO glass using CdCl2 and Na2S2O3 as source materials. The influence of deposition voltage and heat-treatment on the phase compositions, surface morphologies properties of the films,the phase, microstructure and element distribution of CdS thin films were characterized by X-ray diffraction, scanning electron microscopy and energy dispersive spectroscopy techniques. The results showed that the as-prepared cadmium sulfide thin film exhibits amorphous phase before thermal processing and a hexagonal wurtzite CdS structure after the treatment. Deposition voltage is very important, and the cadmium sulfide thin films prepared under the deposition voltage of less than 4.0 V are composed of hexagonal wurtzite CdS phases and hexagonal Cd phase.
