Abstract
In this study, we found that, in perylene microcrystals, luminescence peak position from free-exciton state was gradually shifted to high en ergy side with reducing the crystal size, even if the microcrystals we re fabricated by different kinds of preparation techniques. The life t ime of luminescence from self-trapped exciton state became shorter whe n the crystal size reduced. The main reason was estimated to be based on the change of lattice state.
