摘要
摘要:贵金属等离子体对稀土离子发光晶体材料的发光有着一定的增强作用．本文对基质为60 Bi₂O₃-20SiO₂-20Ga₂O₃的Er³⁺(0.5%)Ag(0.5%)铋化物发光玻璃进行了吸收光谱的测量．利用J-O理论分析了Er³⁺在该基质中的振子强度、自发辐射速率、积分发射截面和荧光分支比等光谱参数．通过振子强度和3个参量${\varOmega _\lambda }\left( {\lambda = 2,4,6} \right)$的拟合计算，根据拟合结果对Er³⁺的各能级跃迁的积分发射截面、荧光分支比等光谱参数进行计算分析，发现这些参数有着较大的数值，表明Er³⁺在本文所研究的基质材料中具有较强的发光能力．

Abstract:Noble metal plasma can enhance luminescence of rare earth ion emitting crystal materials．In the present work, the absorption spectra of Er³⁺(0.5%)Ag(0.5%) bismuth compound luminescent glass in matrix 60 Bi₂O₃-20SiO₂-20Ga₂O₃ were measured．Spectral parameters (intensity, spontaneous emission rate, integral emission cross section and fluorescence branching ratio) of Er³⁺ in this matrix were analyzed based on J-O theory．Oscillator strength and three parameter ${\varOmega _\lambda }\left( {\lambda = 2,4,6} \right)$ fitting were used to calculate Er³⁺ integral emission cross section and fluorescence branch ratio, which were found to be quite large. These data suggest that Er³⁺ ions in matrix used in the present work emit strong luminescence．
