Plasmonics & Surface Plasmon Resonance Explained. from the particle surface, the local refractive index changes, resulting in an SPR wavelength shift.
The clusters show new types of the local surface plasmon resonances compared with single silver nanosphere. Our results The resonance frequency of the oscillation, i.e., the surface plasmon (SP) energy, it is essentially determined by the dielectric properties of the metal and the surrounding medium, and by the particle size and shape. The collective charge oscillation causes a large resonant enhancement of the local field inside aand near the NP. Surface Plasmon Resonance (SPR) is an optical technique used to measure molecular interactions in real time.SPR can occur when plane-polarized light hits a metal film under total internal reflection conditions.

Ulrich's thesis, A local co-operating group (LSG) at IFM monitors and deals with Localized surface-plasmon resonance (LSPR) refers to the collective oscillation of electrons at the interface of metallic structures, which could be produced through the electron-magnetic interaction of the metal with incident light of a specific wavelength (Haes and Van Duyne, 2002; McFarland and Van Duyne, 2003; Hutter and Fendler, 2004). The intensity of UC emission in lanthanide-doped nanomaterials can be estimated by Eq. Surface plasmon resonance can also be tuned based on the shape of the nanoparticle. The plasmon frequency can be related to the metal dielectric constant. The enhancement falls off quickly with distance from the surface and, for noble metal nanoparticles, the resonance occurs at visible wavelengths. Localized surface plasmon resonance creates brilliant colors in metal colloidal solutions.
