    Nano hemi-shell arrays produced by femtosecond laser micro-processing for SERS applications, at Photonics West 2009 (San Jose, CA), Tuesday, January 27, 2009
    Nano-scale periodic structures produce a greatly enhanced near-field at the surface and therefore they are very promising for applications involving Surface Enhanced Raman Scattering (SERS). The ideal shape of the structure is a sphere, a rod, a needle or a hemi-shell. Nano hemi-shell structures obtained by evaporating a thin metal film on small dielectric particles, in particular, have attracted much attention, because their resonant wavelength can be easily tuned by controlling the thickness of the metal film, shells diameter, or the distance between particles. Furthermore, the dielectric... Read more about Nano hemi-shell arrays produced by femtosecond laser micro-processing for SERS applications
