Fig. 4: Relative contributions of the different excitonic processes associated with TADF emission.
From: Probing polaron-induced exciton quenching in TADF based organic light-emitting diodes

Relative contributions are plotted for mCP:4CzIPN OLEDs as a function of current density. a Deactivation of singlet excited state. b Deactivation of triplet excited state.
