A bright orange emission is observed from a combination of red and green emitters. Jang-Joo Kim and co-workers report on page 4105 the creation of orange organic light-emitting diodes using an advanced quasi-host and quasi-emitter concept, where green and red phosphorescent dopants are doped into an exciplex-forming host, realizing a high external quantum efficiency, low driving voltage, and low roll-off efficiency at the same time.
