Research Abstract

Size classification of the nano particles was performed by using DMA (Differential Mobility Analyzer). Nano particles were prepared by pulsed laser ablation of a metal rod in an atmosphere of He gas. Nano particles 5-15 nm in diameter were selectively classified. The particle diameter distributions of the nano-particles were observed by FESEM and TEM. With decreasing voltage to be applied in DMA, the particle diameter distribution shifted toward small diameter. CNTynthesis with these nano particles also studied. Effects of carbon source and hydrogen on CNTynthesis were examined and it was found that by changing the nano particle diameter it is possible to control the structure of CNT.
