Investigation of Plasmonic Properties of a Rhodium Nanoshell Based Optical Nanomaterial

In noble metals, surface plasmons may be induced by incident light, resulting in good plasmonic properties that can widely utilized. this work, an optical nanomaterial based on a spherical nanoshell structure consisting of rhodium and dielectric is proposed. The scattering efficiency electric field are calculated via the finite difference time domain method, respectively varying nanoparticle radius, thickness nanoshell, as well material core. results show under certain conditions ultraviolet regime, two resonance peaks observed spectrum, correlating to different electromagnetic modes. It also demonstrated wavelengths peak intensities effectively tuned changing structural parameters. proposed rhodium-based useful applications devices regime.
