Abstract: | Energy transfer from Bi3+ to Nd3+ is reported in germanate glass. It was found that the excitation range and intensities of the 4F → 4I, 4I emissions are increased several fold when excited through 1S0 → 3P1 absorption of Bi3+. It is shown that the energy transfer is nonradiative. The energy transfer probability and efficiency were calculated from the Bi3+ fluorescence decay rates and intensities. The Bi3+ → Nd3+ energy transfer may be utilized in Nd3+ glass laser. |
