Abstract

The transient 100-fold enhancement and spectral narrowing to 2 nm of the photothermal conversion by solid gold nanospheres under near-infrared excitation with a short laser pulse is reported. This non-stationary effect was observed for a wide range of optical fluences starting from 10 mJ cm^-2 for single nanospheres, their ensembles and aggregated clusters in water, in vitro and in vivo.
