Formation of Various Carbon Nanoclusters from Laser‐Produced Carbon Plasma

Abstract

Laser vaporization of graphite proved to be an unbelievably flexible instrument allowing selective fabrication of various novel forms of carbon (diamond or fullerenes or different types of carbon nanotubes). In this work, the extension of the laser vaporization method to composite fullerene‐containing carbon targets is presented. It is shown that, depending on the pressure in an experimental chamber, different products come out of the ablation plume and get deposited on the substrate. The experimental results of this work allow to suggest a mechanism of formation of different carbon forms from laser‐produced carbon plasma at different experimental conditions.
