摘要：

The optical constants and thickness of CdTe thin films prepared by high-frequency magnetron sputtering method are determined. The synthesis procedure and the results of optical studies of CdTe thin films deposited on the surface of a glass/ITO substrate are given. The optical constants and the band gap of the films under study have been determined. Optical properties (refractive index n(lambda), absorption coefficient alpha(lambda), and extinction coefficient k(lambda)) of the thin films and thickness d can be determined from the transmission spectrum. The dispersion of the refractive index was explained using a single oscillator model. Single oscillator energy and dispersion energy are obtained from fitting. Optical parameters of the films were determined using the Cauchy, Sellmeier and Wemple models.
