APPLICATIONS OF THE CHALCOGENIDE TERNARY THIN FILMS. A REVIEW

Abstract

The chalcogenide ternary thin films chalcogenide glasses offer a new range of infrared transmitting materials to the designer and this review attempts to bring together the currently available data on these glasses. Information is presented on glass preparation, composition, softening temperature, thermal expansion, viscosity, chemical durability, mechanical properties, electrical properties, infrared transmission, refractive index and absorption coefficient, with particular emphasis on infrared transmission. Recent work has shown that impurity absorption bands have limited the infrared transmission of chalcogenide glasses.
