Abstract
Fluorescent quantum efficiencies of green luminescence of the 4S 3 2 level of Er3+ in tellurite glasses was obtained from the fluorescence and absorption spectra of erbium. The quantum efficiency was determined by the comparative method. The influence of the glass phonons on the fluorescent efficiencies is derived from the comparison of erbium fluorescence in tellurite and germanate glasses.
