Gold nanorod has generated great research interest due to its tunable longitudinal plasmon resonance. However, little progress has been made in the understanding of the effect. A major reason is that, except for the metallic spheres and ellipsoids, the interaction between light and nanoparticles is generally insoluble. In this paper, a new scheme has been proposed to study the plasmon

Issue Date: 04 March 2019 Se hela listan på physicsopenlab.org Surface plasmon resonance (SPR) is the resonant oscillation of conduction electrons at the interface between negative and positive permittivity material stimulated by incident light. SPR is the basis of many standard tools for measuring adsorption of material onto planar metal (typically gold or silver) surfaces or onto the surface of metal nanoparticles . Surf ace Plasmon Resonance in Thin Gold Films Martin Magnuson Laboratory of Applied Physics, Linkoping Institute of Technology, S-581 83 Linkoping, May 1993 Abstract Surface plasmon resonance (SPR) is an optical technique that can be used for biosensing. The present work accounts for calculations and 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.
