    摘要: The present invention is directed to the preparation of two groups of transparent glass-ceramics exhibiting high optical clarity and containing essentially only one crystal phase. The first group consists essentially, in cation percent, of______________________________________ SiO.sub.2 20-35 PbF.sub.2 19-23 AlO.sub.1.5 10-20 YF.sub.3 3-7, CdF.sub.2 19-34 ______________________________________ and the second group consists essentially, in cation percent, of______________________________________ SiO.sub.2 20-35 PbF.sub.2 15-25 AlO.sub.1.5 10-20 YF.sub.3 3-7 CdF.sub.2 21-31 ZnF.sub.2 3-7. ______________________________________ These glass-ceramics may be used to fabricate optical waveguide fibers. Also when doped with certain rare earth elements, notably Pr, Er, and Dy, the glass-ceramic materials may be used to fabricate optical amplifiers and lasers.

    摘要: Materials, both glass and glass-ceramic, that exhibit UV-induced changes in light transmission and electrical conductivity behavior. The materials consist essentially, in mole %, of 20-40% SiO2, 10-20% AlO1.5, 35-55% SiO2+AlO1.5, at least 30% CdF2, 0-20% PbF2, and/or ZnF2, 0-15% rare earth metal fluoride, and 45-65% total metal fluorides.
