- Abstract
Nanocrystallized C60 thin films of such as hexagonal, plate-like, and rod-like morphologies were recrystallized by poor solvent immersion, employing 1-propanol, 2-propanol, and butanol respectively. A C60 thin film fabricated by evaporation was immersed in the poor solvent, partially dissolving the surface C60. This was followed by the solvent rapidly reaching a supersaturated state, resulting in the induced recrystallization of the C60. C60 fine high-density crystals were successfully prepared using propanol, with crystal sizes varying between 84 and 141 nm by changing the immersion time. In addition, due to the 1-propanol recrystallizing solvated crystals which were formed through interactions between the solvent and the C60, uniform C60 fine crystals were obtained by the formation of a large number of nucleation sites.
