摘要
Fluorescence enhancement of Eu(III) by Tb(III) in TTA-Phen or BFA-Phen micelle solution was observed. From fluorescence absorption, excitation spectra and the decay time of Eu(III) emission in the complex solution systems, it can be demonstrated that the enhancement effect was the result of two mechanisms, one of which was the 'wrapping effect' of Tb complexes for Eu complexes and the other was intermolecular energy transfer from Tb complexes to Eu(III) ions.
