Through our electrostatic model, we estimate a red-shift in the plasmon resonance peak from a wavelength of about 600 nm to around 1400 nm for Au coated silicon core nanoparticles. This paper investigates the surface plasmon resonance effect, wavelength tuning ranges for different metallic shell nanoparticles, and explores the solar-weighted efficiencies of corresponding core-shell nanoparticle suspensions. Therefore, we are interested in developing a dispersion of core-shell multifunctional nanoparticles capable of dynamically changing their volume ratio and thus their spectral radiative properties. Recent papers have showed that dielectric core/metallic shell nanoparticles yielded a plasmon resonance wavelength tunable from visible to infrared by changing the ratio of core radius to the total radius. The density of silica nanoparticles is approximately. The refractive index of silica is estimated at 1.43. In Figure 4 we report the calculated scattering efficiency (in semi-log scale) for, ,, , and core/shell spherical NPs with metal core radius nm and dielectric. The particles are monodispersed with narrow size distributions. Of particular relevance here are the vast changes to the radiative properties due to the plasmonic nanostructures' large extinction cross section at the corresponding surface plasmon resonance (SPR) wavelength. Our silica nanoparticles are produced via the condensation of silanes to form nanoparticles that consist of an amorphous network of silicon and oxygen via the Stber method. Nanoparticle suspensions are known to offer a variety of benefits for thermal transport and energy conversion.

The ratio of c, the speed of light in a vacuum, to v, the speed of light in a medium, is called the index of refraction, n, of the medium List of refractive indices for common materials Material Because of a complex interaction between an electromagnetic wave (light) and the charges in matter(electrons and protons), a light signal travels more slowly in transparent materials, such as glass or water, than in vacuum. The speed of light in a vacuum is c = 3.00 x 10 8 m/s. In part 2, you will find that the speed of light in plastic varies slightly with the wavelength. In part 1 of this lab you will investigate the bending of light as it travels from air to plastic and plastic to air. This law also applies to the bending of light by lenses and to the guiding of light by the fiber optic cables that carry modern communications signals. The bending of a light ray as it passes from air to water is determined by Snell's law. Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v. If i is the angle of incidence of a ray in vacuum (angle between the incoming ray and the perpendicular to the surface of a medium, called the normal) and r is the angle of refraction (angle between the ray in the medium and the normal), the refractive index n is defined as the ratio of the sine of the angle of incidence to the sine of the angle of refraction i.e., n = sin i / sin r. The Refractive index, also called index of refraction, measure of the bending of a ray of light when passing from one medium into another.
