摘要：
A novel concept for white organic light emitting diodes (OLEDs) enabling the utilization of all electrically generated excitons for light generation is introduced. The key feature is a fluorescent blue emitter with high triplet energy, rendering it possible to harvest its triplet excitons by letting them diffuse to an orange phosphorescent iridium complex.
