Abstract:
A novel method to synthesize Au nanoparticles via a reductive reaction in an ionic liquid containing Au3+ ions was demonstrated using a low-energy electron beam irradiation technique; Au nanoparticles (approximately 122 nm) formed by the incident electron beam were well dispersed and crystallized; this finding opens up the possibility that the use of electron beams and ionic liquids is of key importance in the development of new fabrication techniques for nanomaterials.
