The optical constants and the band gap of the films under study have been determined. Optical properties (refractive index <em>n</em>(λ), extinction coefficient <em>k</em>(λ) and dielectric functions ε(λ)) of thin films and thickness <em>d</em> 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. The material optical parameter such as normalized integrated transmission, zero and high-frequency dielectric constant, density of state effective mass ratio was also calculated.</p> ER -
