The phase equilibrium of glass-ceramic composites prepared by heat-treating Y2O3–Al2O3–SiO2 ternary system were studied by X-ray diffraction measurement. In this series, it was found that the formation of homogeneous glass or glass-ceramics containing only YAG (Y3Al5O12) phase was varied with the starting batch compositions regarded as pseudo-binary (3Y2O3·5Al2O3)–SiO2 system. The glass-ceramics samples obtained by adding Ce were colored in semitransparent yellow and the fluorescence was observed around 530 nm by irradiation of blue light. The intensity of fluorescence was increased with increasing the amount of Ce in glass-ceramics samples. White light was observed by combining the fluorescence and the exciting light. By the energy dispersive X-ray spectroscopy, it was found that the amount of Ce existing in glass phase is more than that in YAG crystal phase.
