| Research Abstract |
In this study, it was found that the kinetics on generation of the organic nanocrystals in the reprecipitation method follow a classic nucleation theory. And then, supersaturation ratio is a critical factor determining the nanoparticle size in the the method. Using these knowledges, regarding the pigment nanocrystals, fabrication of the fine sized pigments nanocrystals with around 15 nm in size could also be achieved. Tn addition, it was shown that the contrast ratio of color filter of nanocrystals prepared by the reprecipitation method gave several times greate than that of pigment crystals fabricated by the conventional technique.
