Studies on the Fluorescent Decay Kinetic Properties and Time-Resolved Fluorimetry of Rare Earth Complexes

Abstract

Abstract: The fluorescent decay kinetic properties of rare earth complexes and the effects with surfactants, additive ligands and synergistic ions were studied. The fluorescence lifetime were same for the different fluorescence emission of each complex. According to the fluorescent decay properties, two time-resolved fluorimetries were proposed for determination of rare earth ion having longer fliorescence lifetime and shorter fluorescence lifetime. Results are satisfactory for the determination of trace amounts europium and dysprosium in oxides of rare earth and synthetic water samples.

Key words: Rare earth, Fluorescence, Time-resolved fluorimetry
