In this study, an interlayer sensitization strategy was employed to manage excitons and achieve highly efficient NIR-OLEDs with an emission peak wavelength exceeding 700 nm.

Additionally, a spacer layer was incorporated to modulate exciton concentration within the NIR emitter and mitigate exciton quenching. By optimizing the doping concentration of TTPA sensitizer, highly efficient NIR OLEDs were achieved. The maximum external quantum efficiency (EQE) reached 6.61 %, with a NIR emission peak at 720 nm.
