We present results for the dependence of the <jats:sup>5<\/jats:sup>D<jats:sub>0<\/jats:sub> lifetime on the excitation wavelength for a wide class of Eu<jats:sup>III<\/jats:sup>\u2010based compounds: ionic salts, polyoxometalates (POMs), core\/shell inorganic nanoparticles (NPs) and nanotubes, coordination polymers, \u03b2\u2010diketonate complexes, organic\u2013inorganic hybrids, macro\u2010mesocellular foams, functionalized mesoporous silica, and layered double hydroxides (LDHs). This yet unexplained behavior is successfully modelled by a coupled set of rate equations with seven states, in which the wavelength dependence is simulated by varying the intramolecular energy transfer rates. In addition, the simulations of the rate equations for four\u2010 and three\u2010level systems show a strong dependence of the emission lifetime upon the excitation wavelength if near\u2010resonant non\u2010radiative energy transfer processes are present, indicating that the proposed scheme can be generalized to other trivalent lanthanide ions, as observed for Tb<jats:sup>III<\/jats:sup>\/Ce<jats:sup>III<\/jats:sup>. Finally, the proper use of lifetime definition in the presence of energy transfer is emphasized.<\/jats:p>","DOI":"10.1002\/chem.201201736","type":"journal-article","created":{"date-parts":[[2012,8,9]],"date-time":"2012-08-09T08:35:50Z","timestamp":1344501350000},"page":"12130-12139","source":"Crossref","is-referenced-by-count":63,"title":["Dependence of the Lifetime upon the Excitation Energy and Intramolecular Energy Transfer Rates: The <sup>5<\/sup>D<sub>0<\/sub> Eu<sup>III<\/sup> Emission Case"],"prefix":"10.1002","volume":"18","author":[{"given":"Rute A.
