A red fluorescent organic light‐emitting device with an unprecedented external quantum efficiency of 10.6% is created by J.‐J. Kim and co‐workers using an exciplex‐forming system as a host for a conventional fluorescent dopant, not showing delayed fluorescence. On page 895, quantitative analysis indicates that over 35% of the total excitons are converted to emission light, clearly indicating triplet harvesting in the system.
