摘要
Transparent glass-ceramics have been prepared by heat-treating 45SiO(2)-20Al(2)O(3)-10CaO-25CaF(2) glasses doped with Eu2+ ions (in mol%). The precipitated crystalline phase in the glass-ceramics was CaF2. TEM observation showed the precipitated crystalline phase had a size of 11-18 nm and dispersed in the amorphous phase without clustering. Fluorescence measurements showed that Eu2+ ions entered into the CaF2 crystalline phase and gave a much stronger emission in the glass-ceramics than in the corresponding glass.
