Energy transfer rates between Nd(II1) and Yb(II1) in glasses of the basic composition 36 PbFz:24 ZnFz:35 CaFs:2 AlF3:3 YF3:4 LaFs were calculated from donor decay curves, and applied for construction of acceptor luminescence curves. The transfer rates are time dependent and the energy loss by Nd(II1
Time-resolved fluorescence lifetime and depolarization measurements are used to investigate electronic excitation energy transfer and trapping in quinizarin-doped aluminosilicate sol-gel glasses. At low quinizarin concentrations donor-donor electronic energy transfer is dominant, however, at higher
Time-resolved fluorescence lifetime and depolarization results are presented for 9-aminoacridine (9AA) doped silicate (SX) and aluminosilicate xerogel (ASX) glasses. At low concentrations the dynamics are dominated by donor-donor energy transfer processes, however, energy trapping by aggregate speci
