Definition of plasmon in English: plasmonnoun ˈplazmɒnˈplazˌmän Physics A quantum or quasiparticle associated with a local collective oscillation of charge density. Example sentencesExamples - The surface plasmons then decay into photons, which are emitted from the surface.
- At each groove, plasmons scatter and radiate some light, while some plasmon energy remains to travel to the next groove.
- 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.
- According to their calculations, when light shines on the largest sphere, it sets up a surface plasmon - a wave of vibrating electrons on the surface of the sphere - that creates an oscillating electric field.
- When light strikes a metallic material, waves of electrons, called plasmons, are generated.
