Abstract
This paper reports optical properties of amorphous chalcogenide thin films of As_2Se_3 of different thicknesses 2000-6800 Å. The transmittance and reflectance of thin films were measured in the wavelength range 500-1000 nm. It was found that the optical band gap increases with film thickness. Variation of refractive index n and extinction coefficient k with thickness have been studied to analyze optical efficiency of the As_2Se_3 thin films. The dielectric behavior of the films has also been studied and high frequency dielectric constants \varepsilon_{\infty} has been estimated as a function of thickness of films.
