Research Abstract	Nano-structured fullerene materials such as C_<60> or carbon onion have been expected to have unique mechanical and electrical properties. However the practical applications of these nano-structured materials were not realized because of the size control limitations of the particle. In this research, it has been investigated to control and increase the particle size of these fullerene based materials using ion implantation technique. It was found that the vacuum annealing treatment of the Ag after the C ion implantation leads to increase the particle size of carbon onion formed in the Ag. This finding would be the key phenomena to synthesize large size fullerene nanoparticle for future applications.
