Innovative methodology identifies exciton quenching types in OLEDs, suggesting ways to improve efficiency.
The performance of an OLED is often marred by an efficiency drop at high brightness. This efficiency roll‐off is primarily caused by exciton quenching. Here, we introduce an innovative methodology for exploring exciton quenching in OLEDs, combining characterisation and simulation. Through multitarget optimization, we can effectively distinguish between triplet‐polaron quenching (TPQ) and triplet‐triplet annihilation (TTA) and investigate their relative contributions during operation.
