Surface Plasmons for Gold Nanoparticles (Meaning More Conductivity)    

Note: The interaction of gold nanoparticles with light is strongly determined by their environment, size and physical dimensions. The oscillating electric fields of a light beam emitted in the vicinity of a colloidal nanoparticle interfere with the free electrons and cause a coordinated oscillation of the electron charge that corresponds to the frequency of visible light. These resonant oscillations are known as surface plasmons. For small (30 nm) monodisperse gold nanoparticles, the phenomenon of surface plasmon resonance causes absorption of light in the blue-spectral part (~450 nm) while red light (~700 nm) is reflected.Gold is a soft and malleable metal with a bright and shiny yellow color that does not…
