Plasmon resonance nanoparticles

In this work, we use the Mie theory to investigate the SPR properties of bimetallic core–shell nanoparticles having a spherical shape and consisting of Drude metals. Localized Surface plasmon resonance (SPR) is an attractive characteristic of metal nanoparticles SPR is a collective oscillation of conduction band electrons in metal nanoparticles excited by the electromagnetic of incident light. From: Organic Electronics, 2014. Plasmons.

These resonant oscillations are known as surface plasmons. For small (~30nm) monodisperse gold nanoparticles, the surface plasmon resonance phenomenon causes an absorption of light in the blue-green portion of the spectrum (~450 nm) while red light (~700 nm) is reflected, yielding a rich red color. Localized Surface Plasmon Resonance (LSPR) system using a glass prism and a multi-layered chip is proposed to detect silver nanoparticles. The model is robust and very general. Expanding localized surface plasmon resonance (LSPR) towards long wavelengths has been the focus of plasmonics for several decades. Compared with the most studied Au and Ag nanoparticles, Cu nanoparticles have intrinsic long-wavelength LSPR, but hard to be facially fabricated due to their sensitivity to oxidation. • Nanoparticles can be used as labels to create DNA microarrays for specific detection of target strands.

Plasmon resonance nanoparticles

Drude Model Plasmonic nanoparticles are particles whose electron density can couple with electromagnetic radiation of wavelengths that are far larger than the particle due to the nature of the dielectric-metal interface between the medium and the particles: unlike in a pure metal where there is a maximum limit on what size wavelength can be effectively coupled based on the material size. What differentiates these particles from normal surface plasmons is that plasmonic nanoparticles also 2008-08-30 · Surface plasmon resonance induced by silver nanoparticles increases the absorption coefficient of the dye in dye-sensitized solar cells , , . Theoretically, this effect can be attributed to the enhancement of the local electromagnetic field near the metal surface when the wavelength of the irradiation source is coincident with the optical absorption of the surface plasmon [4] , [5] .
