Abstract: Energy transfer from a thermally activated delayed fluorescence (TADF) emitter to coupled surface plasmon polariton (SPP) modes of a metal mirror can be utilized to reduce the observed TADF lifetime in a cavity. The Purcell effect reduces the radiative lifetimes of both the singlet (S1) and triplet (T1) states to a similar extent according to the inverse of the simulated Purcell factor (PF). A direct correlation between faster TADF lifetime and enhanced operational stability of fabricated TADF OLEDs was shown due to reduction in triplet mediated annihilation events without any loss in external quantum efficiency (EQE). The design strategies to best utilize the Purcell effect for TADF OLED lifetime elongation were proposed. The extent of Purcell enhancement can be tuned by the choice of TADF emitter, metal electrode, transporting layer properties and device structure design.
