摘要
Several devices using a europium complex Eu(TTA)(3)(DPPz)(TTA=2-thenoyltrifluoroacetonate, DPPz=dipyrido[3,2-a:2('),3(')-c]phenazine) as dopant emitter were fabricated. The performances of these devices are among the best reported for devices incorporating a europium complex as a red emitter. One such device with structure TPD (50 nm)/Eu:CBP (4.5%, 30 nm)/BCP (30 nm)/Alq (25 nm) exhibits an external quantum efficiency 2.1%, current efficiency 4.4 cd/A, power efficiency 2.1 lm/W, and brightness 1670 cd/m(2).
