| Outline of Final Research Achievements |
Glass formation was examined for the sulfide and halide-mixed systems, in which the sulfides are GeS2, Ga2S3, Sb2S3, and the halides are CsX or AgX (X=Cl, Br, I). The properties, such as glass transition temperature, refractive index, and optical properties, and their dependences on halide content were systematically investigated. The CsX of 20 - 30 mol% were incorporated for the GeS2-Sb2S3-CsX systems. It was suggested that phase separation occurs in the GeS2-Sb2S3-AgCl and Ga2S3-Sb2S3-CsCl systems. The absorption edge in the infrared region for the Ga2S3-Sb2S3-CsX glasses shifted to 1 to 2 um compared with those of the conventional sulfide glasses. This indicated that the glass system has a potential applicability for infrared materials.
