Abstract: The Yb 3+ -doped 32CaO-12Y2O3-24Al2O3-31SiO2-1Yb2O3glasses were prepared by a melting method, then the glasses were annealed at 950C, 1050C and 1100C. The crystallographic structures of the glasses annealed at different temperatures were analyzed by XRD, the glass annealed at 1050℃ was observed by TEM. The spectroscopic properties of the glass before and after annealing were investigated. The results show that the glass annealed at 1050℃is YAG glass-ceramics with no impurity crystalline phase. The spectroscopic properties indicate that Yb3+ ions are preferentially entered into the YAG crystal phase. The transparent Yb:YAG glass-ceramics obtained are based on the controlled nucleation and crystallization of CaO-Y2O3-Al2O3-SiO2 system glasses containing Yb 3+ ions.
