[OLED1-2] Analysis Method for Dynamics of Exciton in Organic Light-Emitting Diodes Based on Thermally Activated Delayed Fluorescence Emitters: Magnetic Field Effect as Footprint of Exciton
TADF-OLED, magnetic field effect
We investigated magnetic field effects (MFEs) of thermally activated delayed fluorescence based organic light-emitting diodes (TADF-OLEDs) to understand exciton dynamics under device operation. Our analysis showed a clear evidence of triplet annihilation such as triplet exciton-polaron interaction.
