Abstract
The optical properties of perylene microcrystals in wide range of crys tal size from 50 nm to 1 mu m were measured. The interesting behavior of exciton in microcrystals with less than 200nm was found. For exampl e, with decreasing the crystal size, self-trapped exciton states in mi crocrystals shifted to the high energy side. Therefore, the strong lum inescence from free-exciton was observed, and life time of self-trappe d exciton became shorter.
