Plasmons are the collective oscillations of metal-conducting electrons when an energetic electron passes through them. If these electrons are inside the volume of a metal, they are called volumetric plasmons.The reason for this naming was the similarity of these oscillations of electrons with the oscillations of the particles of the plasma environment.surface plasmon resonance nanoparticles on
