A simple approach for nearly 100% triplet harvesting in conventional fluorescent dopant-based organic LEDs through energy transfer from exciplex is proposed. This approach was realized by (a) using a thermally-activated delayed fluorescence exciplex host to up-convert the triplet excitons to the S1; (b) using an exciplex host with its HOMO and LUMO close to those of the fluorescent dopant to minimize exciton trapping; (c) using an extremely low dopant concentration to minimize triplet-triplet energy transfer from the host to the dopant. Based on this design, the best C545T-doped device employing TAPC:DPTPCz as host shows a low turn-on voltage of 2.8 V and maximum CE, PE, and EQE of 44.0 cd A-1, 46.1 lm W-1, and 14.5%, resp. This approach probably is a general strategy easily extendable to other exciplex host:fluorescent dopant systems.
