Spectroscopy of high-energy states of lanthanide ions

Abstract

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${}_2$.
