摘要

研究了Cr3+,Yb3+,Er3+共掺磷酸盐铒玻璃的吸收光谱和荧光光谱性质。通过测定和计算各种Cr3+,Yb3+,Er3+共掺磷酸盐铒玻璃的光谱参数,初步探明了Ce3+和Cr3+离子浓度含量对Cr3+,Yb3+,Er3+共掺磷酸盐铒玻璃光谱性质的影响。结果表明,CeO2含量为2.8 mol-%,Cr2O3含量为0.08 wt.-%玻璃的光谱性质较好。Ce3+离子价态的变化也对玻璃的光谱性质有重要影响。Ce3+离子的存在更有利于对抽运光的吸收和能量的传递。在Cr3+,Yb3+,Er3+共掺磷酸盐铒玻璃中实现了Er3+荧光寿命达8 ms,受激发射截面为0.8×10-20 cm2的光谱特性,为今后该玻璃的激光实验提供了重要参数。

Abstract

The absorption spectra and fluorescent spectra property of Cr3+, Yb3+, Er3+ co-doped phosphate glass were measured. Some basic properties of spectroscopic properties were calculated. The effect of Ce3+ and Cr3+ concentrations on the spectroscopic properties of the phosphate erbium glasses was also discussed. It could be concluded that the co-doped phosphate glasses of 2.8 mol-% CeO4 and 0.08 wt.-% Cr2O3 have the better spectral properties. On the other hand, the spectral properties are also affected by the valence change between the Ce3+ and Ce4+. Ce3+ is more favorable for the absorption of pumped light and energy transfer. The Cr3+, Yb3+, Er3+ co-doped phosphate erbium glass with fluorescent lifetime of 8 ms and stimulated emission cross section of 0.8×10-20 cm2 was achieved in the study. This provided good basis for the next laser experiments.
