Study of the Optical Properties of Nanoparticles using Mie Theory - TI Journals

Abstract: In this work, we study of the optical properties of nanoparticles using Mie theory. This famous theory is suited to compute accurately the optical cross sections of a spherical particle. According to this theory, we can calculate the place of surface plasmon resonance in optical spectra of spherical nanoparticle. We used Matlab program for simulation of some optical properties like as scattering and extinction cross section area and influence of nanoparticles. Results show that front surface located nanoparticles Ag and Au are the most widely used materials due to their surface plasmon resonances located in the visible range and therefore interact more strongly with the peak solar intensity.
