Abstract

We show that gold nanocrescents can be used as efficient nano-thermosensors taking advantage of the anisotropy of their optical properties. Scattering or fluorescence correlation spectroscopy give access to the local temperature using their rotational Brownian motion. These plasmonic nanoparticules also provide an efficient local heating that can be fully characterized by this technique
