摘要

The spin-Hamiltonian parameters (g factors g(//) g(perpendicular to) and hyperfine structure constants A(//), A(perpendicular to)) of the tetragonal (WO6)(7-) octahedral center in the WO3-doped Zn(PO4)(2)ZnO nanopowders are investigated from the high-order perturbation formulas resting on the two-mechanism (crystal-field and charge-transfer mechanisms) model with a suitable assignment of the absorption band at about 14,370 cm(-1). The calculated results are in keeping with the experimental values. The tetragonal distortion of the (WO6)7(-) octahedral center is also achieved on the basis of the calculation. The outcomes are discussed.
