Femtosecond Surface Plasmon Dynamics of Single Ag Nanostructures

Femtosecond plasmon dynamics of single Ag nanostructures was investigated by the combination of a femtosecond laser system and a time-of-flight photoemission electron microscope (TOF-PEEM). Time-resolved two-photon photoemission spectra of the nanostructures showed that the higher photoelectron yiel...

Description
Summary:Femtosecond plasmon dynamics of single Ag nanostructures was investigated by the combination of a femtosecond laser system and a time-of-flight photoemission electron microscope (TOF-PEEM). Time-resolved two-photon photoemission spectra of the nanostructures showed that the higher photoelectron yield is originated from the slower relaxation time of surface plasmon.
