Incident wavelength resolved resonant SERS on au sphere segment void (SSV) arrays

Sphere segment void (SSV) arrays allow the reproducible engineering of plasmon-polariton modes from the near-infrared to the ultraviolet through the tuning of the void height and diameter. The wavelength dependence of surface-enhanced Raman scattering (SERS) can then in principle be controlled by se...
