  Abstract:  CdS thin films were obtained by potentiostatic electrodeposition on platinum and ITO electrodes from solutions containing CdSO4 and Na2S2O3 at concentration ratios higher than 1. The influence of deposition time, temperature and Cd2+/S2O32- ratio on CdS thin film electrodeposition on platinum electrodes, as well as the film composition were investigated electrochemically, by stripping voltammetry. The morphology and the composition of CdS films obtained on ITO supports were determined by SEM and EDS. It was concluded that the CdS film formation is favored by the increase of electrodeposition duration and electrolyte temperature, as well as by acid media (pH 3) and high Cd2+/S2O32- ratios (200/1).
