Efficient Nd→Yb energy transfer in 0.8CaSiO3-0.2Ca3(PO4)2 eutectic glass

In this work we report the study of energy transfer between Nd and Yb 3+ ions in glasses with the 0.8CaSiO3-0.2Ca3(PO4)2 eutectic composition at room temperature by using steady-state and time-resolved laser spectroscopy. The Nd →Yb transfer efficiency obtained from the Nd 3+ lifetimes in the single doped and codoped samples reaches 73% for the highest Nd 3+ concentration. The donor decay curves obtained under pulsed excitation have been used to establish the multipolar nature of the Nd → Yb 3+ transfer process and the energy transfer microparameter. The nonradiative energy transfer is consistent with an electric dipole-dipole interaction mechanism assisted by energy migration among donors. Back transfer from Yb 3+ to Nd 3+ is also observed. ©2010 Optical Society of America OCIS codes: (160.5690) Rare earth doped materials; (300.6280) Spectroscopy; fluorescence and luminescence.
