New approach for preparation of high-purity sulfide-germanium glasses doped with praseodymium
It has been established that rare earth elements (REE), as alloying additives, are a significant source of hydrogen and oxygen impurity in glasses of Ge – S and Ge – As – S systems. A method has been developed that includes loading germanium in the form of monosulfide and high-temperature annealing...

| description | It has been established that rare earth elements (REE), as alloying additives, are a significant source of hydrogen and oxygen impurity in glasses of Ge – S and Ge – As – S systems. A method has been developed that includes loading germanium in the form of monosulfide and high-temperature annealing of REE and their compounds in sulfur vapor, reducing content of absorbing impurities in sulfide-germanium glasses. Samples of especially pure glasses of Ge42.5S57.5 and Ge35As10S55 composition doped with praseodymium up to 1450 ppm(at) were prepared. The impurity content of hydrogen and oxygen in the form of SH-groups and Ge–O in the best glass samples was 0.02–0.06 ppm(wt) and |
