Abstract
The impulsive photoexcitation of nanoparticles kicks off the time-dependent re-equilibration of the electron gas, ion lattice, and environment. For better understanding and harnessing these processes, for thermoplasmonics or photocatalysis applications, it is paramount to know the dynamic, time-dependent evolution of the temperature of each system subcomponents. We report two different methods to directly deduce the temporal evolution of the electronic and lattice temperature of plasmonic Au nanoparticles excited by ultrashort laser pulses on the fs-ps time scale. © 2023, META Conference.
