| 中文摘要 | The local structures and the electron paramagnetic resonance (EPR) parameters g factors g(\\), g(perpendicular to) and the hypertine structure constants A(\\) and A(perpendicular to) for Er3+ in PbMoO4 and SrMoO4 are theoretically investigated by using the perturbation formulas of the EPR parameters for a 4f(11) ion in tetragonal symmetry. In these formulas, the contributions to the EPR parameters from the second-order perturbation terms and admixtures of different energy levels are considered. Based on the studies, we find that the impurity-ligand bonding angles related to the four-fold axis in the impurity Er3+ centers are reduced by about 1.26 and 1.04degrees compared with those in host PbMoO4 and SrMoO4 Crystals, respectively. The calculated EPR parameters are consistent with the observed values. The validity of the results is discussed. (C) 2003 Elsevier B.V. All rights reserved. |
