Effect Of Annealing On Structural Optical Behavior Of Nanocrystalline Cd_(0.5)Zn_(0.5)S Thin Films

摘要

The synthesis and characterization of nanocrystalline Cd_(0.5)Zn_(0.5)S thin solid films is reported in the present paper. Chemical bath deposition, a direct low cost technique that involves metal ions (Cd~(2+) and Zn~(2+)) source, a complexing agent and a chalcogen (sulphur) source was used to prepare thin films of Cd_(0.5)Zn_(0.5)S at a temperature of 70°C (343 K), with pH of 11 and deposition time of 2.5 hours. The characteristics of the prepared Cd_(0.5)Zn_(0.5)S thin films were investigated by their structural and optical properties and the effect of annealing on these properties were also studied.
