The influence of different antimony content in Ga-As-Sb-S chalcogenide glass system: Modification of physical & spectroscopic properties and fiber forming ability
Ceramics International(2022)
Abstract
In order to improve the fiber drawing performances including the anti-crystallization in fiber drawing process and the mechanical properties, the fourth component of antimony (Sb) was introduced into Ga0.8As39.2S60 glass, and a serial Ga0.8As39.2-xSbxS60 (x = 0, 1, 3,5, 7, 9 and 11) novel chalcogenide glasses doped with 3000 ppmw Dy3+ ions were prepared. The influences of antimony content on the physical properties, spectroscopic properties and fiber forming ability of glass were investigated. The experiment results indicate that the introduction of moderate antimony into glass effectively improves the fiber drawing performance and the spectroscopic properties of Dy3+ ions. The Ga0.8As34.2Sb5S60 composition glass possesses the best performance and it is recommended a good candidate for mid-infrared laser working medium.
