Abstract

We investigated luminescent properties of rare-earth metal complexes and phosphor-rescent molecules doped in a conducting polymer. Electroluminescent (EL) properties in combination of red emissive europium complex of tris(di-benzoylmethane)-mono(4,7-diphenyl-phenanthroline) europium (III) (Eu(dbm)3phen) and blue phosphorescent molecule of bis[(4,6-difluoro-phenyl)-pyridinato-N,C2'] (picolinate) iridium (III) (FIrpic) doped in poly(N-vinyl-carbazole) (PVK) and a new rare-earth complex tris(hexafluoroacethylacetonato) (phenan-throline) samarium(III) [Sm(hfa)3(phen)2] have been investigated as an EL emitter. White EL has been obtained from mixed layer of Eu(dbm)3phen and FIrpic, and EL from Sm complex has been obtained. Energy transfer and the emission mechanisms have been discussed.
