摘要
CdS thin films were deposited from different cadmium salts by using acidic chemical bath deposition (CBD) process. Quality characterizations were performed using different methods such as scanning electron microscopy (SEM), X-ray diffraction (XRD) and photoluminescence (PL). The crystal quality of CdS thin films was improved after CdCl2 thermal annealing at 380 degrees C. A compact structure of CdS thin films can be obtained by using CdCl2 in comparison with the other cadmium salts. Although a Cd/S molar ratio of similar to 1 was used in our experiments, strong PL signals confirmed the high quality of CdS thin films. (c) 2010 Elsevier B.V. All rights reserved.
