英文摘要Two theoretical methods, the perturbation theory method (PTM) and the complete diagonalization (of energy matrix) method (CDM), are applied to calculate the spin-Hamiltonian parameters (g-factors g(parallel to), g(perpendicular to) and hyperfine structure constants A(parallel to), A(perpendicular to), obtained from electron paramagnetic resonance (EPR) spectra) and d-d transitions (obtained from optical spectra) for two tetragonal Cu2+ centers in Ba2ZnF6:Cu2+ crystals. The Cu2+(I) ion replaces the Zn2+ ion at tetragonally compressed octahedral coordination and has the ground state (2)A(1)(vertical bar d(z2) >),whereas the Cu2+(II) ion is at an interstitial site with a square-planar F-coordination and has the ground state B-2(2)(vertical bar d(x2-y2>)). The calculated spin-Hamiltonian parameters and d-d transitions from the PTM and CDM coincide and are in reasonable agreement with the experimental values. This suggests that both methods are effective for the theoretical studies of EPR and optical spectral data for 3d(9) ions in tetragonal symmetry with different ground states. The defect structures of the two Cu2+ centers in Ba2ZnF6:Cu2+ are also estimated. (c) 2009 Elsevier B.V. All rights reserved.
