Fig. 4From: Spatial localization of hotspots in Fano-resonant plasmonic oligomers for surface-enhanced coherent anti-Stokes Raman scatteringa Simulated normalized scattering (blue curve) and NFIE (red curve) of the quadrumer; b Simulated normalized scattering (blue curve) and NFIE (red curve) of the heptamer. The blue and red vertical axes in both diagrams are corresponded to the blue and red curves present in those diagrams. The green dashed (vertical) lines and the red (blue) shaded rectangular regions in both diagrams depict the pump wavelength (780 nm) and the Stokes (CARS) window for the fingerprint region, respectivelyBack to article page
