Research Progress of Eu(Ⅲ)Ligand Polymer Fluorescent Microspheres
With its unique photoluminescence performance,excellent monochromaticity,large stokes shift,high coordination number and Eu(Ⅲ)organic ligand polymer with high quantum efficiency,narrow emission band and high color purity,Eu(Ⅲ)has been widely used in immunoassay,electron fluorescence,optical fiber communication,luminescence imaging and other fields in recent years,especially in the fluorescent labeling of organisms.This article reviews the research and application progress of Eu(Ⅲ)organic ligand polymer system.Firstly,the research background,properties and basic principles of chemiluminescence of Eu(Ⅲ)organic li-gand polymers are described.Secondly,the selection principles of ligands are summarized.Aiming at the prob-lems of concentration quenching and uneven distribution of Eu(Ⅲ)organic ligand polymers,the existing strate-gies of key problems in the compounding of Eu(Ⅲ)organic ligands with different polymers are summarized.Fi-nally,the future development trend of Eu(Ⅲ)organic ligand polymers is prospected.
