摘要

A gadolinium ternary complex, tris ( 1-phenyl-3-methyl-4-isobutyryl-5-pyrazolone) (2,2'-dipyridyl) gadolinium Gd(PMIP)(3)(Bipy) was synthesized and used as a light emitting material in the organic electroluminescent devices. The devices exhibited the green electroluminescent (EL) emission peaking at 513 nm, originating from the Gd(PMIP)3(Bipy). By improving the configuration, the device with a structure of ITO/poly(N-vinylcarbazole) (PVK) (40 nm)/Gd(PMIP)(3)(Bipy) (40 nm)/tris (8-hydroxyquinoline) aluminum (ALQ) (40 nm)/Mg: Ag (200 nm) /Ag( 100 nm) showed higher performance and a maximum luminance of 340 cd . m(-2) at 18 V.
