摘要: 本文采用激光诱导荧光法研究了钐、铕、铽和镝配合物的化学性质、光谱特性与光谱能级间的关系,提出了稀土配合物荧光发射的能量传递模型,并导出速率方程和定态解,根据Dexter固体敏化发光理论讨论了影响荧光产率的各种因素,推导出配体三重态向稀土离子激发态进行有效能量传递的3个条件。

Abstract: In the present paper, the relation among the chemical properties, spectral properties and energy level of the complexes of samarium, europium, terbium and dysprosium were studied by using the laser induced fluorimetry. The model of energy transfer, rate equations and steady state solution in the complexes were established. According to Dexter's theory, the effects on fluorescent yield were discussed. Three elements of effective energy transfer from triplet state of ligands to rare earth ions were suggested.

Key words: Rare earth complexes, Luminescent mechanism, Laser induced fluorimetry
