    摘要: A phototropic glass composition which is devoid of halogen, rare earths, tungsten and molybdenum and which comprises a phase separated melt-fused glass composition containing from about 70 to 95 weight percent CdO, from about 2 to 28 weight percent B2O3, and from about 2 to 28 weight percent of SiO2. Minor proportions of certain other metal oxides, such as the oxides of Ag, Au, Bi, Cu, Hg, In, Pb, Sb, Sn or Te may also be incorporated within the glass composition.
