Paper Abstract

An overview on our latest research on UV plasmonics with Rh and Ga metal nanostructures is presented. We will pay attention to their plasmonic performance and UV tunability. For Ga, its polymorphism will be analyzed and for Rh three characteristic geometries will be studied: tripod star, nanocube and tetrahedron. As an alternative to metals, low heat generation materials for bio applications will be analyzed. A numerical analysis of several candidate low loss dielectric materials that show HRI properties in the UV will be presented. In particular, this analysis will focus on the near-field enhancement and scattering directionality above 3 eV.
