Losses in plasmonics: from mitigating energy dissipation to embracing loss-enabled functionalities (2017, background): “Unfortunately, excitation of highmomentum SPP states is unattainable due to a combination of intrinsic mechanisms associated not only with the material imperfections but also with the very nature of SPP oscillations [17,18,28].”
Single metal nanoparticles: optical detection, spectroscopy and applications (2011, background): “4) are widely used to resolve the excitation dynamics [18] and first probe the equilibration time of the electron bath, typically some tens of femtoseconds.”
Plasmonic doped semiconductor nanocrystals: Properties, fabrication, applications and perspectives (2017, background): “lease of energy to the environment (phonon-phonon coupling) (Figure 27 a and b).[245,246] The variation of the carrier and lattice temperatures after excitation induces a temporal modification of the dielec-”
What’s so Hot about Electrons in Metal Nanoparticles? (2017, background): “LSPR is extremely fast, to the extent that it cannot be accurately measured using conventional ultrafast measurements.(56) A particularly useful approach for studying LSPR dephasing is to measure the linewidths of single metal nanoparticles.”
