Laser ablation synthesis of nano-carbon materials in supercritical fluids

POSTER

Abstract

We report the synthesis of nano-carbon materials by laser ablation of highly oriented pyrolytic graphite in supercritical xenon, using a second harmonic pulsed Nd:YAG laser. Transmission electron microscopy observation and micro-Raman study of synthesized product revealed the presence of nanocrystalline diamond and nanoparticles containing sp$^{3}$ CH$_{x}$ bonds. Furthermore, the synthesis of diamantane and possibly pentamantane and heptamantane was confirmed by gas chromatography-mass spectrometry.
