Abstract
Up-conversion spectroscopy at low temperature is used to probe the symmetry of the sites occupied by the Tm3+ ion in MF2:TmF3 (with M = Sr, Ca, Ba) an d in CdF2:TmF3, NgF. We detected single Tm3+ centers of cubic, trigonal, te tragonal and orthorhombic symmetries and established energy level diagrams. Single Tm3+ centers of cubic symmetry tend to predominate in CaF2:TmF3 as the Tm3+ concentration exceeds 1 at.% (C) 2000 Elsevier Science B.V. All ri ghts reserved.
