摘要: 利用水溶液中表面活性剂分子和有机小分子间的相互作用,成功地制备了具有不同形貌的芘纳米颗粒和纳米棒.对其进行吸收光谱和荧光光谱等光物理行为的研究发现,不同形貌的纳米材料展现出不同的光学性质.同时对纳米材料的形成机制做了初步的分析和讨论.

关键词: 有机纳米材料, 表面活性剂, 模板法, 吸收光谱, 荧光光谱.

Abstract: Pyrene nanomaterials with different morphologies are obtained by template method in an aqueous CTAB system. We found that the as-prepared nanomaterials with different morphologies(nanorods and nanoparticles) exhibited different properties. The mechanism of the preparation was also simply analyzed and discussed.

Key words: Organic nanomaterials, Surfactant, Template method, Absorption spectrum, Fluorescence spectrum
