实验采用静电纺丝技术和特殊设计的并行纺丝针头,制备了一种新型磁光双功能并行微米带。并行微米带分别由Na YF4:Eu3+,Tb3+/PMMA和Fe3O4/PMMA组成,在Na YF4:Eu3+,Tb3+和Fe3O4纳米颗粒中分别加入PMMA。通过XRD,SEM,BM,VSM和PL等现代分析技术,对样品的形貌、磁性和发光性质进行了系统的表征。结果表明:制得的并行微米带具有良好的磁光性能,因为在并行微米带中,磁光纳米颗粒为有效隔离,与Fe3O4/Na YF4:Eu3+,Tb3+/PMMA复合微米带相比,磁光双功能并行微米带具有更优良的性质。这种新型的磁光双功能并行微米带由于其优异的磁光性质,在生物医学纳米材料、药物靶向分离材料和未来纳米器件等众多领域具有潜在的应用,为进一步深入研究磁光双功能微米结构材料奠定了一定的基础。
Experiments using electrostatic spinning technology and specially designed parallel spinning needle, prepared a new type of dual-function magneto-optical parallel micron band. The parallel micron bands are composed of Na YF4: Eu3 +, Tb3 + / PMMA and Fe3O4 / PMMA, respectively, and PMMA is respectively added to the NaYF4: Eu3 +, Tb3 + and Fe3O4 nanoparticles. The morphology, magnetism and luminescence properties of the samples were systematically characterized by modern analytical techniques such as XRD, SEM, BM, VSM and PL. The results show that the prepared parallel microribbons have good magneto-optical properties. Compared with the Fe3O4 / NaYF4: Eu3 +, Tb3 + / PMMA composite microrods, the magneto-optical nanoparticles in the parallel microribbons are effectively isolated. Bifunctional parallel micron tape has more excellent properties. Due to its excellent magneto-optical properties, this new type of magneto-optical bifunctional parallel micron band has potential applications in many fields such as biomedical nanomaterials, drug targeting materials and future nanodevices. In order to further study the magneto-optical bifunctional Micron structure materials laid a solid foundation.
