Analysis of directionality effects in magnetodielectric core-shell nanoparticles by means of polarimetric techniques

Abstract: The influence of increasing the core size of a Ag-Si core-shell nanoparticle has been investigated by using the values of the linear polarization degree at right angle scattering configuration, PL(90º). Changes in dipolar resonances and Scattering Directionality Conditions as a function of the core radius (Rint) for a fixed shell size (Rext = 230 nm) have been analyzed. An empirical formula to obtain the ratio Rint/Rext by monitoring the influence of the magnetic dipolar resonance in PL(90º) has been found.
