What is Localized Surface Plasmon Resonance (LSPR)?
Localized Surface Plasmon Resonance (LSPR) refers to the collective oscillation of conduction electrons in metallic nanoparticles when they are excited by light at specific wavelengths. This phenomenon leads to strong light absorption and scattering, and the resonance frequency is highly sensitive to the nanoparticle's size, shape, and surrounding environment.
