for which the response wavelength of nanoparticles is determined by their shapes,
diameters, as well as distances. In this consideration, the ultrafast laser micro-nano
structuring gives us a good candidate for tuning the optical responses of metal surfaces
via controlling the distributions of produced nanoparticles.
