Description
Summary:The Nd super(3+)/Yb super(3+) co-doped borosilicate glasses are fabricated by using a conventional melt quenching technique in air atmosphere. The Spectroscopic properties of 1.0 mu m emission in Nd super(3+)/Yb super(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 super(3+) donor ions. The glass co-doped with 0.5 mol% Nd sub(2)O sub(3) and 2 mol% Yb sub(2)O sub(3) has a large microscopic parameters 10010 super(-40) cm super(6) s super(-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 super(3+) fiber lasers.
