Abstract

Various tellurium containing chalcogenide glasses from the systems Ge-Se-Te, I-Se-Te and Ge-(As,I)-Se-Te were synthesized and infrared transmission spectra collected from them. The iodide containing glasses tended to have higher long wavelength absorption edges and lower oscillation strengths of the absorption bands produced by hydride impurities than glasses containing no iodine. It was further demonstrated that it is possible to fabricate chalcohalide glasses containing large amounts of germanium. The presence of halogen likely reduces or eliminates hydride contamination through removal as hydrogen halide gas but has no effect on oxide impurities.
