Abstract
The optical properties of AgInSe2 thin films of different thicknesses were studied, where transmittance and reflectance measurements were us ed to calculate the energy gap width, the width of the localized state s and the optical constants n, k. Energy gap width was found to decrea se with film thickness, while the width of the tail of localized state increases. Also, refractive index n was found to increase with wavele ngth, while the absorption index decreases.
