Anisotropy of two-photon excited f–f transitions of Eu2+ in KMgF3
Polarization dependence of sharp intraconfigurational 4f7 transitions of Eu2+ in KMgF3 have been studied by means of two-photon excitation spectroscopy. A new puzzle appears connected with the site-symmetry distortion at the Eu2+ ions and the weakness of third-order spin-orbit corrections, suggestin...

Summary: | Polarization dependence of sharp intraconfigurational 4f7 transitions of Eu2+ in KMgF3 have been studied by means of two-photon excitation spectroscopy. A new puzzle appears connected with the site-symmetry distortion at the Eu2+ ions and the weakness of third-order spin-orbit corrections, suggesting a mechanism for intraconfigurational interaction independent from crystal-field strength and from the site symmetry on the rare-earth ion. Intensity and polarization dependencies of the 8S7/2→6P7/2,6P5/2,6D9/2 transitions have been satisfactorily interpreted in terms of second-order perturbation theory. |
