In this study, we theoretically employed the plasmon-exciton interaction to enhance the spectra in localized surface plasmon (LSP) and PSPP. The tip-enhanced resonance Raman spectroscopy (TERRS) configuration was used to simultaneously enhance both Stokes and anti-Stokes Raman spectra of rhodamine 6G, achieving a huge enhancement factor of approximately 10^13 to 10^15. Furthermore, the plexciton was obtained by employing the Ag nanowire coated with rhodamine 6G, improving the propagation properties.
New methods to improve the properties of surface-enhanced Raman scattering and propagating surface plasmon polaritons (PSPPs) are desirable. In this study, we theoretically employ the plasmon-exciton (plexciton) interaction to enhance the spectra in localized surface plasmon (LSP) and PSPP. The tip-enhanced resonance Raman spectroscopy (TERRS) configuration is used to enhance both Stokes and anti-Stokes Raman spectra of rhodamine 6G simultaneously. We achieve a huge enhancement factor of 10(13) similar to 10(15). Furthermore, we obtain the plexciton by employing the Ag nanowire coated with rhodamine 6G, which improves the propagation properties.
