Paper Abstract

In this paper we present an optical characterization of nanoparticle assemblies containing plasmonic gold nanoparticles and fluorescent upconversion nanoparticles in different ratios. Both the two-photon luminescence derived from gold nanoparticles and the fluorescence originated from upconversion nanoparticles are detected. The optical signatures reflect the composition of the assemblies.
