摘要：

A number of optical applications such as delivery of high power infrared light and optical signal processing require optical materials with photostablity. The photosensitivity of amorphous chalcogeides is well known and thus it is a question, if these materials can be used when photostability is a requirement. Present study reports dependence of photostability with glass network connectivity (given in terms of Mean Coordination Number (MCN)). The investigation of photostability in amorphous Ge6.5As37.5Se56 (MCN-2.50) thin film for UV light (lambda - 365, 436 nm) is done. The usability of the composition is discussed for upcoming optical application.
