Abstract

The CdS thin films were deposited on glass substrate by chemical bath deposition (CBD). The influence of the preparation technique on the structural, optical and electrical properties of the polycrystalline CdS films was investigated using X-ray diffraction (XRD), scanning electron microscopy (SEM) optical transmission. The materials have been prepared using simple aqueous solutions containing Cadmium acetate, as source of Cadmium, and thiourea as source of sulfur and ammonium hydroxide as the complexing agent. The temperature of the bath was maintained at low temperature of 90 ° C. The nanoparticles of CdS was obtained with an energy band gap of 3.8 eV. This study confirms that the energy band gap depends of the grain particle size..
