测量了晶体尺寸从50 nm到1μm范围内茂金属微晶的光学性质。在小于200 nm的微晶体中发现了激子有趣的行为。例如，随着晶体尺寸的减小，微晶中的自陷态激子态向高能方向移动。因此，观察到了自由激子的强烈发光，使自陷态激子的寿命变短。
Abstract The optical properties of perylene microcrystals in wide range of crystal size from 50 ran to 1 μm were measured. The interesting behavior of exciton in microcrystals with less than 200nm was found. For example, with decreasing the crystal size, self-trapped exciton states in microcrystals shifted to the high energy side. Therefore, the strong luminescence from free-exciton was observed, and life time of self-trapped exciton became shorter .
