Triplet-polaron quenching by charges on guest molecules in phosphorescent organic light emitting devices

We use delayed electroluminescence and photoluminescence measurements to study triplet-polaron-quenching (TPQ) mechanism in phosphorescent organic light emitting devices. Results show that the TPQ mechanism is mainly caused by charges within the bulk of the emission layer (EML) rather than by charge...
