Abstract :
A novel approach is reported for imaging and quantifying both the depth and the strength of the optical near-field, of a single colloidal metal nanoparticle, associated with localized surface plasmons. It will be emphasized that this technique relies on a nanoscale molecular molding of the confined electromagnetic field of metal colloids, irradiated at their resonance, by a photo-activated polymer, which enabled us to directly image the dipolar profile of the near-field distribution with an unprecedented resolution, better than 10 nm.Moreover, the approach used enabled one to quantify the near-field enhancement factor.This approach has overcome all the difficulties faced by scanning probeme thodologies to reproduce the form of the near-field of the localized surface plasmons and provides a new way to quantify its magnitude. Furthermore, this approach leads to the production of polymer/metal hybrid nano-systems of new optical properties.
