We proposed a new concept of increasing the plasticity of chalcogenide glasses while maintaining a high glass transition temperature. The main idea of this concept lies in the formation of Ag-Ag metallophilic interactions when silver chalcogenide is introduced into the glass composition. This suggestion was confirmed by the experimental study of glasses based on the Ag₂Se-Sb₂Se₃-GeSe₂system. It was observed that the introduction of 40 mole percent of Ag₂Se into the glass composition leads to the increase of its plasticity by 3.5 times, whereas the glass transition temperature of such glass remains higher than 200 °C. The most typical application area of these materials is infrared (IR) optics. In our case, the addition of silver not only improves the mechanical properties of a glass but also allows one to keep the position of the fundamental absorption edge in the near-IR region (900 nm), which is quite suitable for the aforementioned applications.
