| 摘 要： | 高温熔制摩尔组分为32CaO-12Y2O3-24Al2O3-31SiO2-1Yb2O3的玻璃, 制得的玻璃于950、1050、1100℃三个不同温度进行热处理, 用XRD分析热处理后样品的相变, 用TEM观察1050℃热处理后的样品, 并研究了1050℃热处理前后样品的光谱特性. 研究结果表明: 玻璃在1050℃热处理后, 在玻璃中产生单一YAG相微晶颗粒; 热处理前后样品光谱特性的变化表明热处理后掺杂的Yb 3+离子择优进入到YAG晶格位, 制备得到了透明Yb:YAG微晶玻璃.

| 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. |
