| 摘 要： | 本文研究了镥等三种稀土离子与铽-乙酰水杨酸配合物产生的共发荧光效应。在最佳条件下,Lu3+、Gd3+、Y3+的存在可使铽-乙酰水杨酸配合物的荧光分别增强108,58和73倍。讨论了共发光体系的形成条件和荧光特性。利用Tb-Lu-乙酰水杨酸体系和Tb-Lu-乙酰水杨酸-乙二胺四乙酸-十六烷基三甲基溴化铵体系分析了合成稀土样品和包头稀土标准氧化物中的铽,结果满意,加标回收率为90.5～105.6%,并对共发光的机理和表面活性剂的作用进行了初步探讨。

| Abstract: | A study of the enhancement effect on the fluorescence intensity of terbium acetylsalicylic acid (ASA) system by lutetium,gadolinium or yttrium was carried out.In the presence of these elements the fluorescence of the Tb-ASA system was enhanced by factors of 108,58 and 73. The standard addition method was used for the determinations of terbium in synthetic sample and standard sample and the results were satisfactory. The recovery of terbium was in the range 90.5～105.6%.The fluorescence enhancement mechanism and the effect of surfactant were discussed. |
