Suppression of external quantum efficiency rolloff in organic light emitting diodes by scavenging triplet excitons

Though organic light-emitting diodes are highly desirable for display and lighting applications, efficiency roll-off at high current densities limits its applicability. Here, the authors report a triplet scavenging strategy for improved triplet exciton management and reduced efficiency roll-off.
