ABSTRACT:
A light emitting device comprising a first electrode, a second electrode, an emissive material between the first and second electrodes and a mixing agent separate from the emissive material is disclosed. In certain examples, the mixing agent may be effective to increase a fraction of excitons formed as a singlet state.
