摘要
利用再沉淀法将Perylene/THF溶液注入甲醇和水的混合溶剂中制备了苝纳米薄片,采用扫描电镜（SEM）、吸收光谱对纳米片形貌和光学特性进行了表征,结果表明,注入不同体积Perylene/THF溶液的苝纳米片表现出不同光学特性,同时对纳米片的形成机制进行了初步的分析和探讨。
Perylene nanosheets were prepared by reprecipitation method that perylene/THF solution was injected into a mixed solvent of water and methanol. Morphologies and Optical properties of the perylene nanosheets were investigated by scantling electron microscope （SEM） and UV-Visible absorption spectrum,respectively. The results showed that the perylene nanosheets with different volumes of perylene/FHF solution exhibited different optical properties. The mechanism of the nanosheets formation was also analyzed and discussed.
