Figure 2

(a) Dark-field scattering image of the sample, where the five nanorods with LSPRs at different wavelengths are marked by arrows. (b) SEM images of the nanorods indicated in a in pseudo color. Scale bar, 200 nm. (c) 1–5: normalized PL spectra (solid lines) excited at 633 nm and elastic scattering spectra (dotted lines) excited with a white light source, for the five nanorods selected in a,b. Bottom right panel: Normalized ratio of the PL spectra to the scattering spectra, , of these five nanorods (labeled 1–5) and the PL spectra of a gold(111) single-crystal surface normalized by the value at 648nm (blue line).
