Laser Induced Luminescence of Pr3+ in CaF2 Attributed to Different Local Site Symmetries

  • Chapter
The Rare Earths in Modern Science and Technology

Abstract

The incorporation of trivalent lanthanides into CaF2 is accompanied by a charge-compensation process brought about by interstitial anions, F −i or 02−. This process gives rise to such site symmetries as cubic (Oh), trigonal (C3V), tetragonal (C4V) and others. The optical properties of trivalent lanthanides in such sites are very characteristic. The type of the site-symmetry can be inferred, at least in principle, from the Stark splitting (1,2), and the intensity of the crystal spectrum. The unambiguous identification of the local symmetry of a Pr3+-site requires a combination of techniques such as optical spectroscopy, Zeeman spectroscopy and EPR (3).
