We investigate the physics of photoinduced heat generation in plasmonic structures by using a novel thermal microscopy technique based on molecular fluorescence polarization anisotropy. This technique enables us to image the heat source distribution in light-absorbing systems such as plasmonic nanostructures. ...

[nice: localized heating by shining light on gold nanoparticles/nanowires; localized thermometry by molecular rotational polarization spectroscopy!]
