Abstract
The aim of the present investigation is to study, from theoretical point of view, the nature of the site symmetry of Cu2+ in lithium-sodium mixed alkali cadmium phosphate glasses (hereafter referred to as LiNaCdP) from the nature and splitting of EPR and optical bands as a function of mixed-alkali effect MAE. The host glass is xLi2O + (20-x)Na2O + 20CdO + 59.5P2O5 + 0.5CuO, with x = 10 . The electron paramagnetic resonance spectra for Cu2+ doped mixed alkali cadmium phosphate (LiNaCdP) glasses are calculated from perturbation theory method (PTM), to understand the nature and symmetry of dopant. The results obtained for spin Hamiltonian parameters ( ) indicate that the cooper ion enters in the glass matrix into a tetragonal elongated octahedral site.
