Abstract.
The optical absorption and EPR spectra of Mn2+ ion doped in cadmium maleate dihydrate have been theoretically investigated by diagonalizing the complete energy matrices for a d5 configuration ion in a trigonal ligand-field. According to the suggestion of the optical absorption studies, we assume that the Mn2+ ion enters the host lattice interstitially and the distorted octahedral symmetry for the impurity ion is trigonal. Moreover, the local lattice structure parameters of the system are determined. The results show that the six oxygen ions around the Mn2+ ion are at the same distance R=2.115 Å, and there are three Mn-O bonds forming an angle θ1 of 66.26° with the C3-axis and three others forming an angle θ2 of 43.40°.
