Recent advances in the sensitized luminescence of organic europium complexes

In this paper, recent advances in the synthesis, mechanism of sensitized emission, and luminescent properties of organic lanthanide complexes are reviewed Stress is put on the progress in the development of organic europium complexes and their nanoparticles with excellent visible-light-sensitized and two-photon-sensitized Eu-III luminescence properties. These are of increasing importance because bioanalysis or bioimaging techniques based on such labeled materials will combine the advantages of high sensitivity, high signal-to-noise ratio, deep penetration, and low photodamage to biological samples In addition, the application of long-wavelength-sensitized luminescence of organic lanthanide complexes and their nanoparticles in bioimaging is discussed (C) 2010 Elsevier B V All rights reserved.Chemistry, Inorganic & NuclearSCI(E)80REVIEW9-10,SI972-99025
