Abstract
Abstract The present invention relates to a matrix glass composition for glass doped with dispersed CdS x Se y Te z (x+y+z=1) microcrystallites, which contains P 2 O 5 and/or B 2 O 3 , and ZnO and/or CdO as essential constituent components, in which the total amount of P 2 O 5 and B 2 O 3 is in a range of from 35 to 65 mol %, and the total amount of ZnO and CdO is in a range of from 65 to 25 mol %. The present invention relates also to glass doped with dispersed microcrystallites which comprises a matrix glass composition as defined above as matrix glass, and CdS x Se y Te z (x+y+z=1) microcrystallites precipitated in the matrix glass.
