Paper Abstract

New results on the optical properties of lead telluride films are reported. Semi-transmitting PbTe films were prepared by thermal evaporation. It is demonstrated in detail that substrate temperature during deposition significantly influences the optical properties of PbTe films. The results indicate that PbTe films have the minimum absorption and maximum indices of refraction when deposited at the substrate temperature of 170 degree(s)C and 230 degree(s)C, from wavelengths of 4 to 15 micrometers .
