摘要：

GdBO3:Pr3+ and GdBO3:Pr3+, Yb3+ samples were prepared by solid state reaction at high temperature. XRD patterns, excitation spectra and emission spectra in the Vis-NIR range of the obtained samples were studied in detail at room temperature. The emission of 2F5/2→2F7/2 (980 nm) of Yb3+ was observed under 446 nm excitation, indicating the occurrence of the energy transfer from Pr3+ to Yb3+. The fluorescence intensities varied with different Yb3+ doping concentrations. Luminescence decay curves of Pr3+:3P0 level were recorded as a function of the Yb3+ concentrations and energy transfer efficiency was also calculated. Based on Inokuti-Hirayama model, the energy transfer type from Pr3+ to Yb3+ was derived to be electric dipole-dipole interaction. ©, 2015, Chines Academy of Sciences. All right reserved.
