Paper Abstract

Laser vaporization of graphite was carried out in the presence of high pressure Ar gas of 0.1-0.8 MPa. We compared the growth processes of three synthesized graphitic carbon particles: single-wall carbon nanohorn, multi-layer graphene, and polyhedral graphite particles. We believe graphitization processes occurred from supersaturated hot carbon vapor, dependent on resident carbon densities and their temperature gradients, lead to the growth of the three graphitic particles.
