Pr 3 doped oxyfluoroborate glasses have been prepared with different concentrations of Pr. The absorption, fluorescence, and photoacoustic spectra have been recorded and lifetimes of some levels were measured. The fluorescence decays were found to be non-exponential for the 3 P 0 level. Fluorescence
The spectral migration of energy among Eu 3+ ions in lead-niobium-germanate glass (60GeO 2 -25PbO-15Nb 2 O 5 ) with different Eu 3+ concentrations (0.5, 1, 3, and 5 mol%) has been investigated at low temperature by using time-resolved fluorescence line narrowing (TRFLN) spectroscopy. The spectral fe
