摘　　要：比较了用液相沉淀法或固相法合成的粉体以及最终制得的掺钕钆镓石榴石(neodymium-doped gadolinium gallium garnet,Nd:GGG)陶瓷的性能。结果表明:液相法合成的粉体粒度均匀、粒径小,经干压成型后、在1650℃低真空(1.1×10~3Pa)状态下烧结2～3h得到一定透明度的Nd:GGG陶瓷。用固相法制备的粉体成型后、在1750℃烧结2～3h得到的Nd:GGG陶瓷完全不透明。测得半透明的Nd:GGG陶瓷的吸收光谱和荧光光谱,计算出807nm的峰值吸收截面为1.0×10^(-20)cm^2,最强发射峰在1061nm。Neodymium-doped gadolinium gallium garnet （Nd：GGG） precursor and ceramic were prepared by the liquid phase co-precipitation or solid-state methods, and properties of samples prepared by these methods were studied. The results indicate that the precursor prepared with the liquid phase co-precipitation method has a small particle size. After dry pressing confectioning, the body was sintered at 1 650 ℃ at low vacuum （1.1×10^3 Pa） for 2-3 h, and ceramic with sub-transparency was obtained. When the precursor prepared using the solid state method was sintered at 1 750 ℃ for 2 h to 3 h, a sintered body with non-transparency was obtained. The absorption spectrum and fluorescence spectrum of the subtransparent ceramic were measured, and the absorption at the cross section at 807 nm was calculated as 1.0× 10^-20 cm^2. The strongest emission peak was 1 061nm.
