Title

Engineering Upconversion Emission Spectra Using Plasmonic Nanocavities

Abstract

We show that the upconversion emission spectra of Tm3+ and Yb3+ codoped β-NaYF4-NaYF4 core-shell nanoparticles can be judiciously modified by means of plasmonic nanocavities. Our analysis indicates that more than a 30-fold increase in conversion efficiency to the UV spectral band can be expected by engineering the NIR absorption and the local density of states. The effect of the nanocavity on the resulting radiation patterns is discussed. Our results are exemplified in cylindrical cavity geometries. © 2014 Optical Society of America.
