| 摘要: 综合ZnO-Al2O3-SiO2系和锗酸盐玻璃陶瓷的优点，采用熔融-晶化法首次制备了Ho3+/Yb3+共掺以ZnAl2O4为主晶相的ZnO-Al2O3-GeO2-SiO2系玻璃陶瓷。因[GeO4]四面体和[SiO4]四面体都是玻璃网络形成体，讨论了GeO2取代SiO2对玻璃陶瓷样品硬度及发光性能的影响，最终确定GeO2的取代量为10.55%（w/w）时，玻璃陶瓷综合性能最佳。在980 nm泵浦光的激发下，发现强的绿色（546 nm）和弱的红色（650 nm）上转换发光，并研究了不同Ho3+/Yb3+掺杂比对样品上转换发光的影响，最终结果表明当Ho3+/Yb3+掺杂比为1：11（n/n）时样品荧光强度最强，在绿色上转换发光材料方面具有潜在的应用。 | |

| Abstract: Combining the advantages of ZnO-Al2O3-SiO2 system and germinate glass ceramics, Ho3+/Yb3+ co-doped ZnO-Al2O3-GeO2-SiO2 glass ceramics containing ZnAl2O4 crystalline phase were successfully prepared by melt-crystallization technique for the first time. Because the tetrahedral[GeO4] and tetrahedral[SiO4] are glass network skeleton, Subsequently, the influence of GeO2 instead of SiO2 on the hardness and up-conversion luminescence properties of glass ceramic samples is discussed here. Ultimately, when the quantity of GeO2 instead of SiO2 was 10.55%(w/w), comprehensive performance of the glass ceramic samples were optimum. Under the 980 nm pump light excitation, a strong green emission (546 nm) and a weak red emission (650 nm) are observed. The effect of different doped ratios of Ho3+/Yb3+ on the up-conversion luminescence of samples was studied. The experimental results indicated that the luminescence intensity reaches a maximum when the doped ratios of Ho3+:Yb3+ is 1:11 and the samples have potential application on green up-conversion luminescence material. | |
