Paper Abstract

Upconversion processes have found widespread applications in drug delivery, bio-imaging and solar-cells. In this paper we present a theoretical model that analyzes the impact of a plasmonic shield structure on the quantum yield of upconversion nanoparticles. We use this model to assess the efficiency of NaYF4: Tm3+ Yb3+/NaYF4 core-shell nanoparticles when embedded in a polymer matrix and covered by a metallic can-like structure. We find that as a result of this specific plasmonic structure, the upconversion luminescence from NIR to UV can be increased by a factor of 30.
