Nanoparticles of fullerene C-60, including those as small as 20 nm, were obtained by simple hand-grinding of bulk solids with ail agate mortar and pestle. Crystalline structure, size distribution, and surface characteristics of the hand-ground C-60 nanoparticles were studied. In addition, the C-60 nanoparticles having different sizes were prepared Successfully by fractionating the as-prepared nanoparticles by filtration or centrifugation, and size-dependent optical properties were determined for the C-60 nanoparticle. A linear relationship Was found between the position of the peak at around 350 nm and the diameter of the C-60 nanoparticles.
