Er3+单掺 Yb3+/Er3+掺杂四磷酸盐玻璃光谱性质 Er 3+ -doped Yb 3+ /Er 3+ -doped tetraphosphste glass spectroscopic properties

摘要

制备了Er3+单掺杂及Yb3+/Er3+双掺杂四磷酸盐玻璃，测量了吸收光谱、荧光光谱，用McCumber理论计算Er3+的发射截面，研究了其荧光特性、浓度猝灭及其机制、以及OH基对荧光强度和能量传递的影响，研究发现对四磷酸盐玻璃Yb3+的最佳浓度约为1.82×1021ions/cm3,Er3+最佳浓度约为0.96×1020ions/cm3。

Abstract

The tetraphosphate glasses with Er 3+ and Yb 3+ /Er 3+ dopant were prepared. The absorption and fluorescence emission spectra were measured, and the emission cross-section for 4I 13/2 → 4I 15/2 transition of Er 3+ was calculated by using McCumber theory. Spectroscopic properties, concentration quenching, and the effect of -OH groups on the emission at 1.54 μm in these glasses were investigated with diode laser at 970 nm. The optimization of Yb 3+ and Er 3+ ion concentrations are 1.82×10 21 ions/cm 3 and 0.96×10 20 ions/cm 3 respectively in the glasses.
