Synthesis of m-scale giant fullerene particle

纳米富勒烯材料如碳<60>或碳洋葱具有独特的力学和电学性能。然而，这些纳米结构材料的实际应用并没有实现，因为尺寸控制的限制。在本研究中，我们利用离子注入技术来控制和增加这些富勒烯基材料的粒径。结果表明，C离子注入后的Ag的真空退火处理导致在Ag中形成的碳洋葱的颗粒尺寸增加。这一发现将是合成大尺寸富勒烯纳米粒子的关键现象，为未来的应用。

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.
