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 ...
Fig.6). Furthermore, when changing the thickness of the cavity in order to off tune the cavity and exciton energies completely, the lifetime of the PTCDA emission from the cavity is the same as it is outside the cavity (Supplementary Fig.7), clearly showing that the enhanced quenching of...
Purcell effectlayered metamaterialmetal-dielectric structureeffective medium methodLayered metal-dielectric structures are easy-to-fabricate one-dimensional plasmonic metamaterials. Using the effective media approach, we consider surface plasmons that appear on an interface between such metamaterial and a ...
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...

PL enhanced via high Purcell factor For the on-coupling sample (MoS2/NG3), the excitons almost overlapped with the SPR, indicating significant PL enhancement, as depicted in Fig. 5. The plasmon-assisted PL-enhancement factor (EF) is determined as37,38 $${\mathrm{EF}} = \left| {\frac{...
