摘要：

The preparation and purification of Ge-Ga-S glasses were studied. A purified glass doped with 1000 ppm Pr3+ exhibits a quantum efficiency of 50% in the (1)G(4)-->H-3(5) transition at 1.3 mu m based on fluorescence lifetime measurement and Judd-Ofelt analysis. The effects of Ga and S contents on glass transition and crystallization temperatures, density, refractive index and spontaneous emission probabilities from the F-4(3/2) level of Nd3+ were examined. Compositional dependences of properties are discussed in terms of bond types.
