Abstract

The effects of Tm 3 + ions on the intensity and lifetime of 1.3 μ m fluorescence from Dy 3 + ions in Ge 25 Ga 5 Sb 5 Se 65 glass were investigated, and the energy-transfer mechanisms were discussed. Tm 3 + codoping in Dy 3 + -doped selenide glasses significantly enhanced the 1.3 μ m fluorescence intensity and remarkably increased corresponding lifetime through an efficient energy transfer from Tm 3 + : H 5 3 to Dy 3 + : F 11 2 6 H 9 2 6 . The donor ( Tm 3 + ) excitation was transferred to the acceptor ( Dy 3 + ) by direct electric dipole–dipole interaction or migrated among donor ions by diffusion-limited regime until it came into the vicinity of an acceptor ion, where direct interaction and transfer occurred.
