通过顶晶溶液生长 (TSSG) 方法，从 Li2MoO4 助熔剂中生长出大而透明的 Li3Ba2Yb3(MoO4)8 晶体。晶体的吸收和荧光光谱与单斜晶相的各向异性特征一致。 Yb3+stark 能级的相对能量已根据室温吸收和低温荧光光谱确定。对于 E//X、E//Y 和 E//Z，在 977nm 处的吸收截面计算为 1.90、2.71 和 1.09×10−20cm−2，在 1002nm 处的发射截面计算为 1.18、3.45 和 1.50×10−20cm−2。
A large and transparent Li3Ba2Yb3(MoO4)8crystal has been grown from a Li2MoO4flux by the top seeded solution growth (TSSG) method. The absorption and fluorescence spectra of the crystal have been described consistently with the anisotropic character of the monoclinic phase. The relative energies of the Yb3+stark levels have been determined based on the room temperature absorption and low temperature fluorescence spectra. The absorption cross sections at 977nm are calculated to be 1.90, 2.71 and 1.09×10−20cm−2and the emission cross sections at 1002nm are calculated to be 1.18, 3.45 and 1.50×10−20cm−2for E//X, E//Y and E//Z, respectively.
