Abstract: In this work, the device architecture, triplet harvesting (TH)?system as emitting layer, was developed for the transfer of the triplet excitons from fluorescent emitter to phosphorescent emitter, where they can decay in radiation. This concept of the TH is to transfer the non-radiative triplet excitons from fluorescence to radiative triplet excitons in phosphorescence. The TH for the hybrid blue and white organic light-emitting diodes, which combines a fluorescent with a phosphorescent emitter, has achieved advanced efficiency and reduced efficiency roll-off.
