Abstract

Two series of europium complexes with heterocyclic ligand 1,10-phenanthroline (phen) or β-diketones dibenzoymethane (DBM) and thenoyltrifluoroacetone (TTA) were doped in polyvinylpyrrolidone (PVP) to form composite hybrids. These systems were characterized by X-ray diffractometry, FT-IR and photoluminescent spectroscopy. Eu(phen)₂CI ₃(H₂O)₂ disassociates in the composites due to coordination of C=O of PVP to Eu³⁺ resulting in very different luminescent properties from that of the corresponding complex. Eu(DBM) ₃(H₂O)₂ and Eu(TTA)₃(H ₂O)₂ keep the coordination structure of β-diketones to Eu³⁺, but some supramolecular interactions exist between the complexes and PVP, leading to the slight change of the luminescent characteristics of the composites compared to those of the corresponding complexes.
