本文研究了动物胶对铽离子荧光的影响及增敏作用的最佳条件,测定了络合物组成比并对动物胶的荧光增敏机理作了初步探讨。发现了其他稀土金属离子对铽荧光熄灭效应的大小与稀土金属离子基态光谱项密切相关的规律。本体系可应用于不产生荧光熄灭效应的钪、钇、镧、钆、镥等稀土氧化物中铽的荧光测定,方法简便、快速、不需要用特殊试剂。 In this paper, the effects of gels on the fluorescence of terbium and the optimal conditions of sensitization were studied. The composition ratio of complexes was determined and the mechanism of fluorescence sensitization of gels was also discussed. Found that the rare earth metal ions on the fluorescence quenching of terbium size and rare earth metal ions are closely related to the state of the law. The system can be applied to the fluorescence determination of terbium in rare-earth oxides such as scandium, yttrium, lanthanum, gadolinium and stilbene which do not produce fluorescence quenching effect. The method is simple and rapid and does not require special reagents.
