Abstract Er₂O₃-doped bismuth silicate glasses are prepared by the conventional melt-quenching method, and the Er³⁺:⁴⁺I_13/2 → ⁴I_15/2 fluorescence properties are studied for different Er³⁺ concentrations. Infrared spectra are measured to estimate the exact content of OH- groups in the samples. Based on the electric dipole--dipole interaction theory, the interaction parameter C_Er,Er for the migration rate of Er³⁺:⁴I_13/2 → ⁴I_13/2 in proposed glasses is calculated.
