Red Color GeSe2‐Based Chalcohalide Glasses for Infrared Optics

摘要: GeSe2–Ga2Se3–CsI chalcohalide glasses are synthesized, and their optical properties thermo-mechanical studied. A typical characteristic of the is excellent transparency in red-light region addition to 8–14 μm atmospheric window, which vital importance quality control infrared systems. The short-wavelength absorption edge λs glass system has a distinct blue shift with increasing CsI content, physicochemical interpretations suggested formulated. These present transition temperature (Tg) around 300°C good thermal stability. Consequently, they can be promising candidate materials for optics, although hardness relatively weak.
