Light scattering calculations from Au and Au/SiO2 core/shell nanoparticles
Abstract
Given the importance of the optical properties of Au and Au/SiO2 core/shell nanoparticles, in this article we focus our attention on the light scattering properties of such systems and on a relative comparison. In particular, we report theoretical results of angle-dependent light scattering intensity and scattering efficiency for Au and Au/SiO2 core/shell nanoparticles increasing the Au particle radius from 30 to 130 nm, and for Au/SiO2 core/shell particles changing the core-to-shell sizes ratio. Finally, a comparison between the scattering efficiency of the Au and Au/SiO2 core/shell nanoparticles is drawn. The results of this work can be used in the design of tunable efficiency light scattering devices (biological and molecular sensors, solar cells).
