摘要: 在研究共存元素对钐、铕、铽和镝配合物荧光发射的影响时,人们曾分别观察到这些配合物的荧光强度不但不随某些共存稀土和非稀土离子浓度的增加而降低;而是在一定浓度范围内随共存离子浓度的增加,配合物的荧光发射大大增强,利用这种效应可大大提高这类配合物的荧光分析灵敏度。

Abstract: A new sensitized fluorescence phenomenon was observed by adding some of metal ions to Eu (Sm)-DBM-CPB or Eu(Sm)-TTA-Phen-Triton X-100 system, which is known as a synergistic luminescence effect. The synergistic luminescence effect and its analytical application were studied using laser-induced fluorimetry. The influence of the chemical properties of rare earth ions on the synergistic luminescent effects of above systems is reported. The synergistic luminescence systems can be used for the determination of ultratrace amounts of europium and samarium. Results are satisfactory for the determination of trace europium and samarium in highly pure rare earth oxides and synthetic samples.
