Descripción: Cadmium sulphide (CdS) thin films were prepared by means of the chemical spray pyrolysis technique. The substrate temperature was varied in the range from 200 to 400°C. The structural properties of the semiconductor were characterized by X-ray diffraction; XRD patterns indicated the presence of single-phase hexagonal CdS. Direct band gap values of 2.37-2.41 eV were obtained. The refractive index is reported on depending on the substrate temperature, and was obtained from transmission spectra and from spectroellipsometry measurements. As a consequence, the optical parameters of the films were determined using the Swanepoel, Cauchy, Sellmeier and Wemple models. The resistivity of the films was found to vary in the range 10³ 10(5)Ω.cm, depending on the substrate temperature.
