Plasmonic related processes

Nowadays, plasmonics covers a wide scientific field at the frontier between the optics, the solid state physics and the chemistry with various applications in enhanced spectroscopies, nano-optics, nano-medicine... The plasmon is defined as the collective oscillation of the electron cloud in a metal and is related with electronic (excitation of the electrons) and optical properties of a material. It can be optically excited inside a nanoparticle (NP).

The plasmon excitation then induces several processes:
  1. a large field enhancement around the NP (nano-optics),
  2. local heating (thermo-plasmonics),
  3. “hot electrons” creation that can react with molecules (molecular plasmonics).
