TI  - Chalcogenide Glasses
AB  - Chalcogenide glasses, which are among the technologically very important materials, contain at least one chalcogen element as a major constituent and their utilization ranges from infrared (IR) optics applications to phase–change, optical–electrical data–recording. The interest to spectacle glasses exhibiting transparency in the IR region of the optical spectrum coincides with the mid–twentieth century. Firstly, heavy metal oxides were investigated and the transparency limit was extended from 3–5 μm (classical oxide glasses) to 7–8 μm wavelength. The widespread usage of infrared optics in the 20th century has led to the need for new IR materials and to increase the IR transparency limit over 8 μm and scientists have tried chemical compositions of S, Se and Te in the 6th group of the periodic table. Compared to oxide glasses, their mechanical strength and thermal stability are considerably lower and the calorimetric glasses form a new glass group with semiconductor properties. In this article, a brief overview of the definition, historical development, structure, properties and potential applications of chalcogenide glasses dating back to the early 1950s is given.
