摘要
以Al2 O3 、Y2 O3 、Nd2 O3 为起始原料 ,用固相合成方法在 15 0 0℃、2h条件下合成了掺钕钇铝石榴石 (1.1at.%Nd∶YAG)粉料。研究表明 ,在固相反应过程中 ,首先形成中间相Y4Al2 O9(YAM)、YAlO3 (YAP)而最终形成单相Y3 Al5O12 (YAG)。将上述粉料经等静压成型并在低真空状态下于 175 0℃烧结 3h ,获得呈半透明状态的Nd∶YAG陶瓷 ,其相对密度达到 98.6 8% ,显微结构均匀 ,荧光性能与 0 .
Nd-doped yttrium aluminum garnet (1.1at% Nd∶YAG) powder was synthesized by the solid-state reaction at 1500℃ for 2h using Al_2O_3,Y_2O_3 and Nd_2O_3 as starting materials. The results show that the intermediate phases, Y_4Al_2O_9(YAM)and YAlO_3 (YAP), are formed firstly, and finally single-phase Y_3Al_5O_(12)(YAG) is made in the process of the solid-state reaction. The synthesized powder compacts isostatically pressed were sintered at 1750℃ for 3h under vacuum. The relative density of the semi-transparent Nd∶YAG ceramics obtained is 98.68%, and it has uniform microstructure.The fluorescence spectrum for 1.1at% Nd∶YAG ceramics is similar to that for 0.9at% Nd∶YAG single crystal.
