Here we introduce the polariton-enhanced Purcell effect in blue PHOLEDs. We find that plasmon–exciton polaritons9 (PEPs) substantially increase the strength of the Purcell effect and achieve an average Purcell factor (PF) of 2.4 ± 0.2 over a 50-nm-thick emission layer (EML) in a ...
The Purcell effect, the enhancement of the radiative decay rate in a microcavity, can reduce the triplet density and hence the probability of destructive high-energy triplet-polaron5,6 and triplet-triplet annihilation events4,5,7,8. Here, we introduce the polariton-enhanced Purcell effect in ...

Tip-enhanced spectroscopy of plexcitons. Panel A: the strongly confined ∣Ez∣field in a plasmonic nanogap cavity surrounding a single isolated CdSe/ZnS quantum dot (QD) and a tilted Au tip induce coupling between the plasmon and exciton. Panels B: Measured PL spectra for the QD, cavity pla...
