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 800 nm and 532 nm short light pulses. Decay of fluorescence contains several components with different spectral and temperature dependencies in the range from 10 ns to 1000 μ s . The temporal evolution of a fluorescence spectrum is discussed. The model of the relaxation of excitation is proposed to explain the experimental data.
