Thin films of cadmium sulphide have been successfully deposited by chemical bath deposition (CBD) technique using a mixed aqueous solution of cadmium sulphate, thiourea, and triethylamine. The films were characterized using a variety of techniques. Powder X-ray diffraction analysis shows that the as-deposited thin film has the hexagonal (wurtzite) structure. Scanning electron microscope (SEM) micrographs show the film surface consists of clusters with a globular surface morphology. Energy dispersive X-ray diffraction (EDAX) analysis confirmed the film to be consistent with the formation of cadmium sulphide on silica glass slide. The band gap, determined from optical absorption spectroscopy, was 2.42 eV which is consistent with other published results.
