【摘要】 根据Pr3+ /Yb3+ 共掺碲酸盐玻璃在 980nm附近的吸收谱及 1.3 1μm处的发射谱 ,研究了玻璃样品光谱特性随稀土离子浓度变化的规律。结果表明 :在Yb3+ 离子浓度不变的情况下 ,1.3 1μm处的发光随着Pr3+ 离子浓度的增加 ,其强度先增后减 ,并在浓度为 0 .15mol%时达到最大值 ,同时根据Judd -Ofelt理论计算了稀土离子的光辐射特性更多还原

【Abstract】 The effect of Pr 3+ ,Yb 3+ ion concentrations on spectroscopic properties were investigated according to the absorption spectra around 980nm and the emission spectra around 1.31μm.It was found that the fluorescent intensities around 1.31μm increase and then decrease with the increase of Pr 3+ ion concentration,and the maximum value occurs at 0.15mol% in the case of fixed Yb 3+ ion concentration.The radiative properties of the transitions were also calculated by Judd-Ofelt theory.更多还原
