摘要
Poly(vinyl alcohol) (PVA) was added to a water suspension of perylene nanocrystals prepared through the reprecipitation method. The growth of the nanocrystals can be sustained by the protecting effect of PVA. At the same time, the monomer emission of perylene nanocrystals is enhanced and the lifetime of the excited state is prolonged after the addition of PVA, owing to the interaction between perylene nanocrystals and PVA molecules.
