Abstract
Using the superposition model (SPM) of the crystal fields (CF), we modeled the crystal field parameters (CFPs) acting on Mn2+ ions, doped in the triclinic sites symmetry of Zn2SiO4. The modeling of the CFPs of the system has been done using the ascent in symmetry method by approximating the triclinic site symmetry by a higher symmetry, like the orthorhombic or the cubic symmetries. In both cases, orthorhombic and cubic symmetry, the crystal field parameters were calculated. The CFPs calculated, in the case of tetrahedral symmetry, were used for the diagonalization of the Mn2+ Hamiltonian of the system. The obtained results are compared with the experimental data..
