Enhanced Fluorescence Emission of Bonding Type Rare Earth Complexes Eu(MAA)₃Phen

Abstract:

Rare earth fluorescent complexes monomer with activated double bonds was synthesized by using Eu as the central atom, Methacrylic acid and 1, 10-Phenanthroline monohydrate as ligand. The structure of resultant Eu (MAA)₃Phen was determined by infrared spectrum, ultraviolet spectrum and element analysis, and the fluorescence property of the complexes was tested by fluorescence spectra and fluorescence microscopy. Compared with conventional luminescent materials, this resultant complexes show greater fluorescence intensity. The analysis has revealed that with the increase of rare earth ion concentration from 4×10^-5mol·L^-1 to 4×10^-3mol·L^-1, the fluorescence quenching phenomenon appeared in the complexes solution.
