Ultrafast Dephasing of Surface Plasmons in Silver Nanoparticles: The Role of Capping Agents

Not Accessible

Your library or personal account may give you access

Abstract

The dephasing times of localized surface plasmons in silver colloidal nanoparticles stabilized with different capping agents are measured. The short T2 measured are strongly dependent on the stabilizer. The results are supported by DFT calculations.
