采用固相反应法制备了Ln 3+（Ln=Nd，Sm，Eu，Gd，Dy，Ho，Er）掺杂的Y3 GaO 6化合物，测量了它们的吸收光谱、光致发光光谱、激发光谱和时间分辨光谱。X射线粉末衍射结果表明：（Y_（0.96）Ln_（0.04））_3Ga_（O_6）的晶格常数随着三价Ln ~（3+）离子半径的减小而减小，表明Ln ~（3+）离子取代了Y ~（3+）离子进入晶格。光谱分析表明，在紫外-可见光区有明显的吸收。在可见光和红外区的强发射表明Y3 GaO 6是一种适合于掺稀土激光晶体和荧光粉的基质材料。
Ln3+(Ln=Nd, Sm, Eu, Gd, Dy, Ho, Er)-doped Y3GaO6compounds were prepared by solid-state reaction, and their optical spectra such as absorption, photoluminescence, excitation and time-resolved spectra have been measured for Ln=Nd, Sm, Dy, Ho, Er. X-ray powder diffraction shows that the lattice parameters of the compounds (Y0.96Ln0.04)3GaO6decrease with the decrease of the radii of trivalent Ln3+ions, indicating that Ln3+ions have substituted for Y3+ions in the lattice. Optical spectra show that there are obvious absorptions at ultraviolet to visible region. The strong emissions in visible and infra-red region show that Y3GaO6is a suitable host for rare-earth-doped laser crystal and phosphor materials.
