摘　　要：本文研究了稀土离子对铕(Eu)-2-噻吩甲酰三氟丙酮(TTA)-氯化甲基三烷基铵(N263)-Triton X-100体系的共发光能力,提出用放大倍数作为共发光能力比较的定量标准,用能量转移效率和能量利用率来预测稀土离子的共发光能力。该方法适用于不同条件或不同体系之间共发光能力的定量比较。The ability of fluorescence enhancement effect by different rare earth ion was compared in europi-um-thenoyltrifluoroacetone-trialkyl ammonium chloride-Triton X-100 system. Magnification times were made as comparable quantitative standard of columinescence effect. The efficiency of energy transfer and energy utilization was used to predict the result of fluorescence enhancement effect by different rare earth ions. This method can be applied to the quantitative comparison of columinescence effect between different test conditions and systems.
