Extraordinary properties of metal nanoparticles (NPs) such as photo-heating, emissive properties, Fano resonance, etc. are due to the unique capability of NPs to confine an electromagnetic radiation at the nano-scale (the so called Surface Plasmon Resonance). Nowadays, NPs are used in several research fields ranging from liquid crystal based sensors to medicine. In this talk, I present a simplified (quasi-static approximation) theoretical approach, which reveals very useful to understand both the capability of NPs (immobilized on a substrate or even in the bulk) to produce heat in a quite controllable way and the behavior (e.g. emissive properties) of NPs in the presence of a gain medium.
