释义	plasmon /ˈplazmɒn / noun Physics A quantum or quasiparticle associated with a local collective oscillation of charge density.It is based upon the coupling of plasmons (charge density oscillations) excited by light in thin metal films, with waveguide modes in a dielectric layer overcoating the metal film....

The surface plasmons then decay into photons, which are emitted from the surface. Origin 1950s: from plasma + -on.
