• Gold nanoparticles Optical properties and implementations

    The SPR wavelength of gold nanoshells can be controlled by changing the shell thickness Decreasing the thickness of the gold shell from 20 to 5 nm leads to SPR red shift about 300 nm which is attributed to the increased coupling between the inner and outer shell surface plasmons for thinner shell particles
