Surface plasmons are collective excitations of conduction electrons at the interface between a metal and dielectric that are stimulated by electromagnetic radiation.
A surface plasmon polariton (SPP) occurs when surface plasmons interact strongly with electromagnetic radiation.
Surface plasmon resonance (SPR) is another synonym for SPP and refers to the coherent (resonant) oscillation of the surface conduction electrons excited by electromagnetic radiation.
A localized surface plasmon resonance (LSPR) is a nonpropagating SPP confined to nanostructured surfaces.
The term plasmonics is often used to cover the various phenomena sustained by SPP and SPR types of light-matter interactions.
