Structure and Morphology of Solid C60/C70 and C60 Grown from Benzene Solution

Abstract

Crystallites of C₆₀/C₇₀ mixture and pure C₆₀ have been produced from benzene solution by evaporating the benzene solvent. The new forms of solid carbon have been examined by electron microscopy with particular attention to the structure of crystallites with platelet shape. Electron diffraction patterns and high-resolution images reveal that they have an hcp structure (a=10.1±0.1 Å, c=16.5±0.2 Å) with stacking faults of molecular layers perpendicular to the c-axis.
