Schwarzite-like carbon flakes with argon-bubbles were fabricated by using nickel and argon ions irradiation on graphite in proper order. Complete phase separation between carbon and argon was distinguished by high-resolution transmission electron microscopy (HRTEM) images and X-ray energy dispersive spectroscopy (EDS) measurements. Raman scattering and electron diffraction (ED) pattern reveal that as-grown flake has a phase structure of the glassy carbon-like. Possible growth process of this nanoscale material of Schwarzite-like carbon embedded with Ar-bubbles was briefly discussed. (C) 2003 Elsevier B.V. All rights reserved.
