Improved efficiency by a fluorescent dye in red organic light-emitting devices based on a europium complex

By doping a fluorescent dye in the emissive layer, we realized high efficient red organic light-emitting diodes (OLEDs) based on a europium complex. The OLEDs realized by this method showed pure red emission at 612 nm with a full width at half maximum of 3 nm. The Commission International de L`Eclai...

Summary:By doping a fluorescent dye in the emissive layer, we realized high efficient red organic light-emitting diodes (OLEDs) based on a europium complex. The OLEDs realized by this method showed pure red emission at 612 nm with a full width at half maximum of 3 nm. The Commission International de L`Eclairage Coordination keeps approximately the same as the emission of pure Eu 3+. The maximum brightness and EL efficiency reached 2450 cd/m 2 at 20 V and 9.0 cd/A (6.0 lm/w) at a current density of 0.012 mA/cm 2, respectively. At the brightness of 100 cd/m 2, the current efficiency reached 4.4 cd/A.
