摘要
以N，N-二甲基甲酰胺为溶剂，乙酸锌为前驱物，苯乙烯-马来酸酐共聚物为大分子稳定剂，采用溶液化学法，制备了氧化锌纳米粒子。通过紫外-可见吸收光谱（UV-Vis）、荧光光谱（PL）、透射电子显微镜（TEM）等方法对合成的ZnO纳米粒子样品进行表征。结果表明，所合成样品具有量子尺寸效应，样品UV-Vis吸收光谱在350nm给出氧化锌纳米粒子的特征吸收峰，样品PL光谱显示在410nm处可产生明显的荧光发射。氧化锌纳米粒子的尺寸在50-100nm且粒径分布较窄，表明苯乙烯-马来酸酐共聚物对氧化锌纳米粒子的表面起到了良好稳定作用。
ZnO nanoparticles were synthesized by using N, N-dimethyl formamide as solvent, zinc acetate asprecursor and poly（styrene-co-maleic anhydride） as polymer stabilizer through wet-chemical route. The synthesizedZnO nanoparticles were characterized by UV-Vis absorption spectroscopy （UV-Vis）, fluorescence spectroscopy （PL）and transmission electron microscope （TEM）. The results show that the obtained ZnO nanoparticles could give quan-tum size effect. UV-Vis absorption spectra showed characteristic absorption peaks of the ZnO nanoparticles located at350 nm. PL spectra showed obvious fluorescence emission located at 410 nm. The sizes of ZnO nanoparticles are in therange of 50--100 nm with a narrow size distribution. The results demonstrate that poly（styrene-co-maleic anhydride）could act as a good polymer stabilizer for the formation of ZnO nanoparticles.
