Abstract
We report on the production of large carbon-based toroids (CBTs) from fullerenes. The process involves two-step laser irradiation of a mixed fullerene target (76% C60, 22% C70). Transmission electron microscopy (TEM) clearly identifies toroidal-shaped structures as well as Q-shaped constructs. The typical diameters of the CBTs are â¼0.2-0.3 μm with tubular diameters of â¼50-100 nm, but toroids as wide as 0.5 μm are observed making them nanostructures on the verge of being microstructures.
