Spectroscopic properties and energy transfer study of Nd3+/Yb3+ co-doped in borosilicate glass for 1.0 μm emission

Abstract The Nd 3+ /Yb 3+ co-doped borosilicate glasses are fabricated by using a conventional melt quenching technique in air atmosphere. The Spectroscopic properties of 1.0 μm emission in Nd 3+ /Yb 3+ co-doped borosilicate glasses are investigated under 808 nm excitation. The luminescence decay curves show a nonexponential character, the energy transfer microscopic parameters and transfer efficiencies are calculated. Results indicate that the energy transfer takes place via nonradiative electric dipole–dipole processes and is enhanced with the concentration of Nd 3+ donor ions. The glass co-doped with 0.5 mol% Nd 2 O 3 and 2 mol% Yb 2 O 3 has a large microscopic parameters 100×10 −40  cm 6  s −1 , high transfer efficiencies 73.58% and long fluorescence lifetime 0.3 ms at 1020 nm, which is of great potential as a candidate material in the development of multiple-pump-channel Yb 3+ fiber lasers.
