Abstract :
Organic electroluminescent (OEL) devices with trivalent thulium (Tm3+) complex (Tm(acetylacetonato)3(monophenanthroline) [Tm(AcA)3phen]) as an emitting layer were fabricated. Double-layer type cells with a structure of glass substrate/indium–tin oxide (ITO)/poly-(vinylcarbazole) (PVK)/Tm complex/Al exhibit blue luminescence when forward bias dc voltage was applied. Spectrally-narrow OEL emission at 482 nm from Tm3+ ion in Tm complex was observed.
