摘要/Abstract

摘要： 选取大π共轭体系4-(4-甲氧基苯亚甲基)-2-苯基-5(4H)-噁唑酮作为研究对象,采用再沉淀法制备其纳米晶体,通过研究溶剂、温度、搅拌速度、搅拌时间等因素对所形成的纳米粒子的形貌尺寸的影响,成功制备出了形貌较单一的纳米棒和纳米带结构并进一步考察了它们的紫外吸收和发射光谱,结果表明随着纳米粒子尺寸的增加,其吸收光谱和荧光光谱均出现红移,荧光量子效率随着粒子尺寸的增大略有增大.

关键词: 有机纳米粒子, 形貌控制, 光学特性

Abstract: In this paper,we successfully prepared nanoparticals,nanocuboid,nanorod and nanobelt of 4-(4-methoxybenzylidene)-2-phenyloxazol-5(4H)-one in different size using reprecipitation method.The morphology and size of nanoparticles are mainly controlled by solvent and temperature.The higher temperature benefits for large size particles.The absorption and emission spectra of nanobelt show bathochromic shift in comparison with other nanoparticles.

Key words: organic micro/nano particles, morphology control, optical property
