    • In order to avoid confusions about the vocabulary used in this paper, it could be useful to point out that all the following processes are equivalent and describe the same phenomenon: internal thermalization, electron-electron collision, electron-electron scattering, build-up of Fermi-Dirac electron distribution, hot electron thermalization, formation of a hot electronic gas, establishment of an electronic temperature. The external thermalization describes the electronic energy transfer toward the lattice via electron-phonon interaction and is also called the cooling process.

    • note
    • The electronic temperature rise was estimated from the gold heat capacity, the adsorbed optical energy (according to the laser pulse intensity, the spot size and the sample absorbance) and the concentration of gold nanoparticles. However, these values should be taken with care since uncertainties on the spot size are quite large (±30%). Furthermore, as demonstrated in this work, a significant part of the optical energy is directly dissipated toward adsorbates and is therefore not redistributed among other electrons to build-up the Fermi-Dirac distribution.
