摘要

采用高温固相法制备了一系列单掺或双掺Pr

和Yb

的GdBO

材料

分别测试分析了材料的物相结构和发光性质。在446 nm蓝光(Pr

)激发下

检测到Yb

的近红外特征发射

表明样品中存在Pr

到Yb

的能量传递。Pr

的掺杂浓度一定时

样品的发光会随着Yb

掺杂浓度的改变而发生变化。通过对比不同掺杂情况下Pr

能级的衰减曲线

发现随着Yb

的掺杂浓度的增加

该能级的荧光寿命不断缩短;同时利用不同条件下的衰减特性计算得出不同Yb

掺杂浓度样品的能量传递效率。用Inokuti-Hirayama模型分析表明Pr

-Yb

能量传递类型为偶极子-偶极子相互作用。

Abstract

GdBO

:Pr

and GdBO

:Pr

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

5/2

7/2

(980 nm) of Yb

was observed under 446 nm excitation

indicating the occurrence of the energy transfer from Pr

to Yb

. The fluorescence intensities varied with different Yb

doping concentrations. Luminescence decay curves of Pr

level were recorded as a function of the Yb

concentrations and energy transfer efficiency was also calculated. Based on Inokuti-Hirayama model

the energy transfer type from Pr

to Yb

was derived to be electric dipole-dipole interaction.
