Abstract
Fluorescence decay dynamics of photo-excited p-element (Bi, Pb, Sb, Sn)-doped and Al-codoped germanate glasses have been studied over a wide range of time scales and intensities upon excitation with and short light pulses. Decay of fluorescence contains several components with different spectral and temperature dependencies in the range from . The temporal evolution of a fluorescence spectrum is discussed. The model of the relaxation of excitation is proposed to explain the experimental data.
