Studies of the EPR and optical spectra for Cr3+-doped KAl(MoO4)2 crystal

The EPR parameters (zero-field splitting D and g factors g(parallel to), Deltag = g(parallel to) - g(perpendicular to)) and the first excited-state splitting delta(E-2) for Cr3+- doped KAl(MoO4)(2) crystal are calculated from the high-order perturbation formulas. In the calculations, the parameters are obtained from the optical spectra and structural data of the studied system. The results show good agreement with the observed values. (C) 2004 Elsevier B.V.
