摘要
Perylene nanoparticles with different sizes were prepared by reprecipitationmethod. It is found that the nanoparticles show size-dependent optical property. Electrondiffraction patterns indicate that all the nanoparticles of different sizes are in crystallinestate. The rapid growth of the nanoparticles during the aging process could be slowed downeffectively by the addition of cationic or anionic surfactants.
