AbstractOn the basis of complete energy matrices for a 4f(3) configuration ion in trigonal symmetry ligand-field, the optical and EPR spectra of Nd3+ center in Bi4Ge3O12 have been reasonably explained. The results indicate that the Nd3+ ion do not occupy the actual Bi3+ site, but departure from the ideal host position along the C-3 axis by about 0.07 angstrom. The new set of crystal-field parameters that can well account for the Stark levels and EPR parameters have been obtained from the superposition model. Moreover, the influence of orbital reduction factor k and local distortion parameter Delta Z on EPR parameters is analyzed. (C) 2012 Elsevier B.V. All rights reserved.
