H. Kasai et al., Preparation of C-60 microcrystals using high-temperature and high-pressureliquid crystallization method, CHEM LETT, (12), 2000, pp. 1392-1393
Using reprecipitation technique from high temperature and high pressure liq
uid, C-60 microcrystals with size of about 40 nm and narrow size distributi
on could be fabricated in the dispersion Liquid. And it was found that the
optical properties of C-60 microcrystals were also dependent on crystal siz
e in a similar manner as the other pi -conjugated organic microcrystals.
