Erratum to: Strong coupling of multiple plasmon modes and excitons with excitation light controlled active tuning

After the publication of this article [1], the authors found that the energy range of the photoluminescence (PL) spectrum in the top panel of Figure 3c is incorrect. The correct version of Figure 3 is shown below, and the caption of the figure remains the same. This error does not affect the conclusions of the article.

Figure 3:

Analyses of PL spectra for Ag NW-WSe₂ coupled systems. (a) PL spectra of Ag NWs on monolayer WSe₂ with different E ₂. The red arrow marks the redshift of SP_L mode. The two plexciton peaks are labeled as P₁ and P₂. The PL spectrum of bare monolayer WSe₂ without Ag NW is plotted at the bottom. (b) Energies of fitting peaks in the experimental PL spectra as a function of E ₂ (orange, blue, and green dots). The black lines are the calculated results for the scattering in Figure 2b. The black hollow dots are the energies of SP_L mode extracted from the corresponding scattering spectra. (c) Top: PL spectrum for a Ag NW-WSe₂ coupled system when SP₂ mode is close to exciton energy (E ₂ = 1.650 eV). Middle: Normalized PL spectrum resulting from dividing the top spectrum by the PL spectrum of bare WSe₂. Bottom: Scattering spectrum for the same coupled system.
