Optical properties of n-CdSe sub 1-x Te sub x polycrystalline thin films

Abstract

Absorption coefficient, {alpha}({lambda}), and energy gap, E{sub g}, of CdSe{sub 1-x}Te{sub x} thin films were determined from the measured transmittance and reflectance at normal incidence of light in the wavelength range 450-2500 nm. The thin film were electrochemically prepared on glass plates coated with conducting thin films of SnO{sub 2}. A combined method from Goodman and Lubberts was used to determine the absorption coefficient and its dependence on the wavelength. The evolution of the optical gap versus the composition of Te in CdSe{sub 1-x}Te{sub x} was made and a value of 1.4 eV of the optical gap was obtained for the composition of CdSe{sub 0.65}Te{sub 0.35}. (orig.).
