Abstract

Energetic heavy and light ion effects on gold nanoparticles were probed by irradiating 20 and 60 nm diameter nanoparticles with either 3 MeV Cu³⁺ or 10 keV He⁺ ions in situ inside of a transmission electron microscope. Both ion species caused sintering, agglomeration, and ablation of the nanoparticles via sputtering, although at different rates.
