Fluorescent properties of a dendritic ligand europium complex incorporated in polymethylvinylsiloxane

A dendritic europium complex, Eu(BCPD)3Phen, has been incorporated into polymethylvinylsiloxane (PMVS). Its fluorescent properties have been investigated by fluorescence emission spectra and lifetime measurements. According to the fluorescence emission spectra, the Judd–Ofelt parameters Ω2, Ω4 of Eu(BCPD)3Phen/PMVS have been calculated. The radiative decay rate Arad, the non-radiative rates Anrad, the lifetime τ and the luminescent quantum yield η were analyzed also.
