Abstract

The Letter is devoted to the problem of the optical anisotropy of the rare-earth ions occupying low-symmetry positions in crystals. The crystal, field multiplets arising from LSJ terms of Eu3+ and. Tb3+ ions in the crystal field of calcium, tungstate scheelite (CaWO4) are analyzed with regard to the experimental data on the low temperature photoluminescence and cathodoluminescence spectra. The selection rules as well as an angular (polarization) dependence of the two-photon absorption are discussed.
