noun
- Plural of plasmon; a quantum of plasma oscillation in a solid or metal, representing a collective excitation of free electrons.
Usage: physics; technical
Examples
- Plasmons in metallic nanoparticles can be excited by light, causing strong optical absorption.
- Surface plasmons are used in biosensing applications to detect molecular interactions.
- The interaction between plasmons and photons creates hybrid quasiparticles called polaritons.
- Researchers study plasmons to develop more efficient solar cells and optical devices.
- Plasmonic metamaterials exploit plasmons to achieve unusual electromagnetic properties.
