| Abstract: | In the present paper, cadmium zinc selenide (Cd0.5Zn0.5Se) thin films were deposited on glass substrates by chemical bath deposition with optimized deposition parameters. 2-mercaptoethanol was used as a capping agent. The as-deposited thin films were annealed at 300, 500 and 700 °C and then subjected to various structural, morphological and optical investigations. The effect of the presence of capping agent and annealing on these properties was discussed. The phenomenon of phase transformation occurred during annealing. The optical band gap energies were found in the range 2.37–1.7 eV with respect to the annealing temperatures. |
