Abstract

The intensively luminescing mixed-ligand europium compounds were synthesized of the composition Eu(C10H11F7O2)3D, where C10H11F7O2 is heptafluorodimethyloctanedione, D is either 1,10-phenanthroline (C12H8N2), triphenylphosphine oxide (C18H15PO), hexamethylphosphoramide (C6H18N3PO), benzotriazole (C6H5N3), or phenylguanidine [(C6H5NH)2 =NH]. The luminescent properties of europium compounds in the crystalline state and in a polymer matrix of high-pressure polyethylene (HPPE) and polyvinyl chloride (PVC) and kinetics of the luminescence intensity decay under UV radiation were studied. The most photo-resistant in HDPE and PVC was found to be Eu(C10H11F7O2)3Ph3PO.
