چکیده انگلیسی
Er2O3-doped TeO2-ZnO-La2O3 modified tellurite glasses were prepared by the conventional melt-quenching method, and the Er3+: 4I13/2â4I15/2 fluorescence properties have been studied for different Er3+ concentrations. Infrared spectra were measured in order to estimate the exact content of OHâ groups in samples. Based on the electric dipole-dipole interaction theory, the interaction parameter, CEr,Er, for the migration rate of Er3+: 4I13/2â4I13/2 in modified tellurite glass was calculated. Finally, the concentration quenching mechanism using a model based on energy transfer and quenching by hydroxyl (OHâ) groups was presented.
