Hot-Electron Intraband Luminescence from Single Hot Spots in Noble-Metal Nanoparticle Films

Disordered noble-metal nanoparticle films exhibit highly localized and stable nonlinear light emission from subdiffraction regions upon illumination by near-infrared femtosecond pulses. Such hot spot emission spans a continuum in the visible and near-infrared spectral range. Strong plasmonic enhance...
