AbstractThe local lattice structure and electron paramagnetic resonance (EPR) spectra have been studied systematically by diagonalizing 364 x 364 complete energy matrices for a f(11) ion in a trigonal ligand-field. By simulating the calculated Stark levels and EPR parameters to the experimental results, the shift parameters are determined for Er3+ ions in BaF2 and SrF2. The results show that the trigonal center is attributed to an interstitial F- ion located at the [1 1 1] axis of the cube, and the nearest ligand close to the charge compensator has a displacement towards central ion by 0.042 angstrom for L center in BaF2:Er3+ and 0.026 angstrom for J center in SrF2:Er3+, respectively. Moreover, the relationships between g-factors and shift parameter Delta Z as well as orbit reduction factor k' are discussed. (C) 2012 Elsevier B.V. All rights reserved.
