Thermometric Calibration of the Ultrafast Relaxation Dynamics in Plasmonic Au Nanoparticles

Marzia Ferrera, Giuseppe Della Valle, Maria Sygletou +8

The excitation of plasmonic nanoparticles by ultrashort laser pulses sets in motion a complex ultrafast relaxation process involving the gradual re-equilibration of the system's el…

Sharp spectral variations of the ultrafast transient light extinction by bimetallic nanoparticles in the near-UV

Tadele Otomalo, Lorenzo Di Mario, Cyrille Hamon +6

Noble metal nanoparticles exhibit localized plasmon resonance modes that span the visible and near-infrared spectral ranges and have many applications. Modifying the size, shape, a…

Diameter dependence of the temperature dynamics of hot carriers in photoexcited GaAsP nanowires

Aswathi K Sivan, Lorenzo Di Mario, Yunyan Zhang +6

Nanowires (NWs) with their quasi-one-dimensionality often present different structural and opto-electronic properties than their thin-film counterparts. The thinner they are the la…
