摘    要:制备了不同 Al(PO3)3含量的掺铥系列氟磷酸盐玻璃,研究了其结构、热稳定性和光谱性质. 研究了不同摩尔百分数 Al(PO3)3掺杂下 Cr3+/Tm3+/Ho3+共掺氟磷酸盐玻璃在 2.0μm 处的发光特性. 并且用Judd-Ofelt理论计算了强度参量,并由此计算了激发能级的自发辐射跃迁速率、辐射寿命、荧光分支比等光谱参量. 结果表明,随着 Tm3+浓度增加,2.0μm 处发光的强度逐渐增强. 证明了Tm3+(3F4) →Ho3+(5I7)能量转移是非常有效的,并与掺杂浓度有关. 关键词: 氟磷酸盐玻璃 能量传递 荧光光谱 吸收光谱

关 键 词:氟磷酸盐玻璃  能量传递  荧光光谱  吸收光谱

Abstract:Fluorophosphate glasses with various Al(PO3)3 contents were prepared,and their structure,thermal properties and spectral properties were studied.The emission properties at around 2.0μm of Cr3+/Tm3+/Ho3+ co-doped fluorophosphate glasses with different mole fractions of Tm3+ and Ho3+were studied. The spectral strength parameters Ωt(t=2,4,6) of those glasses have been calculated. Meanwhile,the spectral parameters, including the oscillator strength,spontaneous emission probability and branching ratios of Ho3+, have been calculated. The results show that the 2.0μm emission intensity gradually grows higher with the increase of the mole fraction of Tm3+. The Tm3+→(3F4) →Ho3+(5I7) energy transfer in (Tm3+/Ho3+) co-doped fluorophosphate glasses is very efficient, and it is dependent on the doping concentration.
Keywords:fluorophosphate glasses  energy transfer  fluorescence spectra  absorption spectra
