Abstract

The optical response of metal nanoparticles is dominated by the electrons and thus is extremely rapid. For bulk metals, the relaxation of hot electrons is understood as an electron-phonon interaction.¹ The relaxation of hot electrons in nanoparticles is more complex and affected by size and embedding medium.²
