Abstract
The optical absorption spectra of Er3+ in single crystals of InCl3 and ScCl3 have been obtained between 14,000 and 29,000 cm−1. The observed crystal field splittings are interpreted in terms of crystal potential of symmetry 3m for ScCl3 and of symmetry 2m for InCl3. There is however found, that for both cases the splittings will be approximately explained by a crystal potential of cubic symmetry. The employed hostlattices are of special interest, because the ions of the iron series can occupy the same sites as the rare earth ions.
