Thin films of chemical composition Ge 20 Se 80 and Ag 6 (Ge 0.20 Se 0.80 ) 94 are prepared by thermal evaporation technique. The optical properties of these thin films are determined by a method, based only on the transmission spectra at normal incidence, measured over the 400-2000 nm spectral range
