摘要:

讨论了镧系离子4f ${N-1}$ 5d激发态在基质材料中的研究进展和前景。采用从头计算方法对Ce $^{3+}$在LiYF $_4$中的晶体场和自旋轨道参数进行了计算,得到了4f $^1$和5d $^1$构型的晶体场和自旋轨道参数.我们讨论了使用激发态吸收探测的电子和几何结构的4f $^{N-1}$ 5 d激发态的可能性更详细,我们说明了这些想法与计算Yb $^{2+}$离子SrCl $_2$。

英文摘要:

We discuss recent progress and future prospects for the analysis of the 4f${N-1}$5d excited states of lanthanide ions in host materials. Ab-initio calculations for Ce$^{3+}$ in LiYF$_4$ are used to estimate crystal-field and spin-orbit parameters for the 4f$^1$ and 5d$^1$ configurations. We discuss the possibility of using excited-state absorption to probe the electronic and geometric structure of the 4f$^{N-1}$5d excited states in more detail and we illustrate these ideas with calculations for Yb$^{2+}$ ions in SrCl$_2$.
