Abstract

In this study, we examined the function of halogen iodine acting as a glass network modifier in green chalcogenide glasses based on the Ge-S system. We obtained a series of Ge-S-I glasses and determined their glass-forming region. We then recorded the physical, thermal, and optical properties and studied the effect of halogen iodine on Ge-S-I glasses. Results show that these glasses have relatively wide optical transmission window for infrared (IR) applications. The softening temperature of Ge-S-I glasses varies from 210.54°C to 321.63°C, this temperature fits well with some kinds of high-temperature polymers, such as PES and PEI, the polymers serve as protective layers with high strength and flexibility, thus simplifying the fabrication processes of IR chalcogenide glass fiber. Finally, we performed a purification process to eliminate impurities and to improve optical spectra.
