Perylene nanoparticles with different sizes were prepared by reprecipitation method. It is found that the nanoparticles show size dependent optical property. Electron diffraction patterns indicate that all the nanoparticles of different sizes are in crystalline state. The rapid growth of the nanoparticles during the aging process could be slowed down effectively by the addition of cationic or anionic surfactants.
