摘要：
Energy transfer leading to electroluminescence of a lanthanide complex, Eu(Fod)(3)MK (Fod = heptafluoro-dimethyl-octanedionate, MK=4, 4'- bis(N, N-dimethylaminobenzophenone) doped into PVK host is investigated. The optical properties of pure Eu(Fod)(3)MK and its doping in PVK show that the PVK host can efficiently transfer energy to europium ions through a co-ligand of MK due to good spectrally overlap. Light-emitting diodes (LED) consisting of PVK doped with 1-5 wt% of Eu(Fod)(3)MK also demonstrates this energy transfer. Organolanthanide complexes doped into a wide-gap conducting polymers would lead to efficient and pure red organic LEDs to solve the full colour conjugated polymer displays. (C) 2004 Elsevier B.V.
