Control of the optically induced heating of gold nanoparticles

Giovanna Palermo, Roberto Caputo, Antonio De Luca, Cesare Paolo Umeton

Abstract


Gold nanoparticles (GNPs) have proven to be good nano-sources of heat in the presence of specific electromagnetic radiation. This process, in fact, becomes strongly enhanced under plasmon resonance. In particular, the amount of generated heat and the consequent temperature increase depend on the number of GNPs that are collectively excited and on their relative distance. As a result, the regime of heat localization is deeply controlled by this last parameter.
