Abstract

Abstract: ITO/TiO₂/CdS composite thin films were successfully prepared by electrodeposition of CdS nanoparticles on ITO/TiO₂. The XRD and SEM results indicate that the CdS particles are hexagonal phase and the particle with cauliflower-like cluster distribute very uniformly in size. The growth of CdS nanoparticles can be effectively controlled by adjusting the electrodeposition potential and time. With the fall of potential and the decrease of time, the particle sizes decrease. The UV-Vis spectra indicate that the nanoparticles prepared under the different conditions have a very obvious size quantization effect. Furthermore, the electrodeposition conditions have very obvious effects on the photoelectronic performance of the obtained ITO/TiO₂/CdS films.

Key words: Electrodeposition, CdS, Composite thin film, Photoelectric performance
