摘　　要：采用原位聚合法制备分散性良好、粒径在300nm以下、兼具磁性能与荧光性能的Fe3O4／壳聚糖纳米微球，通过XRD、IR和SEM等对产物的组成、结构和微观形貌进行表征，利用荧光光谱分析Fe3O4壳聚糖纳米微球进行光学性能测试，实验结果表明，通过交联反应，Fe3O4被壳聚糖所包覆，产物显示出了非常好的荧光性能，并且在外加磁场下具有明显的磁响应行为。Fe3O4/chitosan nanospheres with size below 300 nm are synthesized by in situ polymerization, which has some advantages, such as good dispersion, high magnetic and fluorescent properties.The composition of the product, structure and microstructure were characterized By XRD, IR, and SEM; the optical performance of Fe3Odchitosan nanoparticles was analyzed by fluorescence spectroscopy tests. Experimental results show that Fe3O4 were coated with chitosan by cross-linking reaction, and Fe3O4/chitosan nanospheres show both excellent fluorescent properties and magnetic response under exterior magnetic field.
