Crystal Field Studies on MgGa2O4: Ni2+

The energy levels scheme of octahedrally coordinated Ni(2+) ion in single crystal, powder nano-single crystal, ceramics and glass-ceramics of MgGa(2)O(4) host matrix, has been calculated in the exchange charge model of crystal field. The parameters of the crystal field acting on the Ni(2+) ion are calculated from the crystal structure data, after optimization of the geometry of the system. The energy level schemes have been calculated by diagonalization of the crystal field Hamiltonian of this system. The obtained results were compared with experimental data; a good agreement were demonstrated, which confirm the validity of the model and used method.
