What is Plasmonics and How Does It Affect Photon Emissions?
Plasmonics involves the study of plasmons, which are collective oscillations of free electron gas at the surface of metallic nanoparticles. When these plasmons interact with light, they can enhance local electromagnetic fields, leading to increased photon emissions. This enhancement is utilized in Surface-Enhanced Raman Spectroscopy (SERS), biosensing, and photothermal therapy.
