Preparation of C60Microcrystals Using High-Temperature and High-Pressure Liquid Crystallization Method

Using reprecipitation technique from high temperature and high pressure liquid, C60 microcrystals with size of about 40 nm and narrow size distribution could be fabricated in the dispersion liquid. And it was found that the optical properties of C60 microcrystals were also dependent on crystal size in a similar manner as the other π-conjugated organic microcrystals.
