Rare-Earth Ion-Host Lattice Interactions. 4. Predicting Spectra and Intensities of Lanthanides in Crystals.

Abstract

In the first three reports of this series, a method was established for predicting the crystal field parameters, Bkm, of triply ionized lanthanides in crystals. These Bkm for even-k define the crystal field that determines the observed Stark splittings. In this report, the latest values for quantities necessary to derive the Bkm are used in an attempt to isolate the source of these large discrepancies. A new analysis using free-ion wave functions is performed on the spectra of Nd and Er in CaWO4 to determine more accurate tau factors for these ions.
