Abstract
Formation of carbon nanoparticles with perfectly spherical shape and d iamond structure (diamond nanospherulite) by laser-ablating a variety of carbon samples in water is reported for the first time. The studies reveal that molten carbon nanoparticles; generated by laser ablation are quenched directly by water and end up as diamond nanospherulites, possibly due to the high pressure arising from surface tension and the high stability resulting from termination of dangling bonds with hydr ogen, atoms.
