Singlet–singlet exciton annihilation (SSA) is found to be a critical factor for the decomposition of blue thermally activated delayed fluorescence (TADF) emitters in organic light-emitting diodes (OLEDs).

Triplet Triplet Annihilation

The initial luminescence loss of fluorescent OLEDs utilizing triplet–triplet annihilation is not only caused by quenching of singlet exciton with neutral quenchers but also by that of triplet excitons with positively charged quenchers.
