CHARACTERIZATION OF CdS THIN FILMS SYNTHESIZED BY CHEMICAL BATH DEPOSITION USING GLYCINE AS COMPLEXING AGENT

摘要

In this report, using the chemical bath deposition, we have employed glycine as an alternative complexing agent for the synthesis of CdS thin films. The films were deposited on glass substrates at 80 °C. The product was characterized with X-ray diffraction, atomic force microscope, optical absorption and X-ray photoelectron spectroscopy (XPS). Homogeneous CdS thin films with hexagonal crystalline structure and energy band gap of 2.53 eV were obtained after deposition process. The high purity of the sample was corroborated by the XPS measurements.
