摘要：

Eu-polymer complexes containing naphthoate (Nap) ligand were synthesized through copolymerization of Eu(Nap)(2)AA with methyl methacrylate or styrene. Their luminescent properties were investigated. The Eu-polymer phosphors exhibited an intense red emission under UV excitation, the emission intensities were much stronger than that of Eu(Nap)(2)AA complex and that of Eu(Nap)(2)AA-doped polymers of the same Eu content. Energy transfer processes and environmental effects were found to make contributions to the luminescence enhancement. Typical relationships between emission intensity and Eu content exhibited some extent of concentration quenching in our studies. However, D-5(0) lifetime results suggested that the quenching phenomena can not be accounted for by deactivation of D-5(0) State through exchange or multipolar interactions. Ligand energy migration along or cross many chains can interpret the emission concentration quenching phenomena reasonably. (C) 1998 Elsevier Science S.A.
