Development of Multi-physics Modeling of Plasmonics in the UV Region Using Transition Metals

Abstract

Herein, we report the effect of parametric variations on the plasmonic behavior of the transition metals i.e. Pd, Rh, Cr. UV plasmonics is critical for many applications like bio-molecule detection, surface-enhanced spectroscopies, photothermal therapies, photonic integrated circuits, etc especially in the UV region. Noble metals like Au, Ag, Pt are restricted to the visible region. Only there are very limited candidates for UV plasmonics viz. Al, Pt, etc. In order to explore prominent candidates for the UV region, the plasmonic properties of transition metals like Cr, Rh and Pd have been systematically studied. Rh has been found as a strong contender in the deep UV region. Particle size variation studies suggested that selectivity can be introduced in metals like Rh and Pd. This work will provide new insights in the development of UV plasmonics.
