Abstract

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
