论文摘要
对六和七个折叠协调的参数化水晶场分析均显示了C $ _ {1} $对称SM $^{3+} $中心，y $ _ {2} $ _ {2} $ sio $ _ {5} $，基于扩展光谱数据，将基础范围跨越到光学区域。激光位点选择性激发和荧光光谱以及沿多个晶体学方向进行的Zeeman吸收光谱，除了先前确定的$ g $ tensors $^{6} $ h $ _ {5/2} $^{4} $ g $ _ {5/2} $ a $ _ {1} $状态。最终的分析给出了与实验能级和磁分裂的良好近似，得出了与其他灯笼离子一致的晶体场参数，可用于此类分析。
Parametrized crystal-field analyses are presented for both the six and seven fold coordinated, C$_{1}$ symmetry Sm$^{3+}$ centers in Y$_{2}$SiO$_{5}$, based on extensive spectroscopic data spanning the infrared to optical regions. Laser site-selective excitation and fluorescence spectroscopy as well as Zeeman absorption spectroscopy performed along multiple crystallographic directions has been utilised, in addition to previously determined $g$ tensors for the $^{6}$H$_{5/2}$Z$_{1}$ and $^{4}$G$_{5/2}$A$_{1}$ states. The resultant analyses give good approximation to the experimental energy levels and magnetic splittings, yielding crystal-field parameters consistent with the few other lanthanide ions for which such analyses are available.
