Influence of the Reaction Temperature on Cd_1-xZn_xS Thin Films with Chemical Bath Deposited

Abstract:

Cd_1-xZn_xS thin films were deposited on soda-lime glass substrates with chemical-bath deposition (CBD) using cadmium acetate, zinc sulfate, thiourea, ammonia and ammonium acetate aqueous solution at different with stirring. All the samples were annealed at 200 °C for 60 min in the air. The crystal structure, surface morphology, thickness and optical properties of Cd_1-xZn_xS thin films with increasing ammonia concentration were studied with X-ray diffraction (XRD), scanning electron microscopy (SEM), step height measurement instrument and spectrophotometer respectively. The results revealed that Cd_1-xZn_xS thin films had cubic crystal structure and the intensity of the diffraction peak decreased gradually as reaction temperature rose and the average crystal size was from 7.0 nm to 8.9 nm. All of Cd_1-xZn_xS thin films had a granular surface with some smaller pores. The Cd_1-xZn_xS thin films band gap was from 2.68 eV to 2.83 eV. The transmission of film deposited at 80 °C was highest. The suitable reaction temperature was from 70 °C to 80 °C.
