采用顶部籽晶法生长了尺寸为60 × 26 × 22 mm 3的Tb：LCB晶体。X射线粉末衍射（XRPD）分析表明，Tb 3+的引入没有改变LCB晶体的结构。用电感耦合等离子体发射光谱法测定样品中Tb 3+的含量为3.76 × 1020 ions/cm 3。采用最小偏差法在室温下精确测量了Tb：LCB晶体的主折射率，并拟合了Sellmeier方程。在室温下用X-、Y-和Z-切割晶体测量了非偏振吸收和发射光谱。根据Judd-Ofelt理论计算了5D4态的自发跃迁几率、荧光分支比和辐射寿命。在368 nm激发下的非偏振和偏振发射性能也进行了评估。测量了对应于5D_4 - 7 F_5跃迁的543 nm发射的衰减时间。实验结果与计算结果吻合较好。
Tb3+doped La2CaB10O19(Tb:LCB) crystal with dimensions of 60 × 26 × 22 mm3has been grown by the top-seeded solution growth (TSSG) method. X-ray powder diffraction (XRPD) analysis shows that the introduction of Tb3+does not change the structure of LCB crystal. Tb3+content was determined by inductively coupled plasma optical emission spectrometry to be 3.76 × 1020ions/cm3. The principal refractive indices of Tb:LCB crystal were accurately measured at room temperature by using the minimum deviation method, and Sellmeier equations were fitted. The unpolarized absorption and emission spectra were measured at room temperature by usingX-,Y-, andZ-cut crystals. According to the Judd–Ofelt theory, the spontaneous transition probabilities, fluorescence branch ratio, and radiation lifetime of5D4state were calculated. The unpolarized and polarized emission properties under the 368 nm excitation were also evaluated. The decay time of the 543 nm emission corresponding to5D4–7F5transition was measured. The experimental results agree well with the calculated ones.
