Electrospinning synthesis of Fe3O4/Eu(DBM)(3)phen/PVP multifunctional microfibers and their structure, luminescent and magnetic properties 作者:Qin, RF (Qin, Ruifei)[ 1 ] ; Liu, LN (Liu, Lina)[ 1 ] JOURNAL OF MATERIALS SCIENCE-MATERIALS IN ELECTRONICS 卷: 32 期: 14 页: 18741-18750 DOI: 10.1007/s10854-021-06393-5 出版年: JUL 2021 在线发表日期: JUN 2021 文献类型:Article 查看期刊影响力 摘要 Multifunctional Fe3O4/Eu(DBM)(3)phen/PVP ((DBM: dibenzoylmethane, phen: 1,10-phenanthroline, PVP: polyvinyl pyrrolidone) microfibers were constructed by simple electrospinning process. The structure and morphology of the microfibers were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images. The diameters of pure PVP microfibers and the microfibers doped only with Fe3O4 nanoparticles (NPs) were uniformly distributed, with an average diameter of about 360 nm. When 3% Eu(DBM)(3)phen complex and Fe3O4 NPs were both added to the precursor for electrospinning, the microfibers became very inhomogeneous in diameter. The photoluminescent properties of pure Eu(DBM)(3)phen complex and composite microfibers were also studied. The characteristic emission peaks of Eu3+ appeared in the composite microfibers. The intensities of emission and excitation spectra gradually decrease with adding more Fe3O4 NPs. The unit mass of the pure europium complex in some composite microfibers gave stronger luminescence than the pure europium complex. The fluorescence lifetime of D-5(0) state in the composite microfibers is longer than that of pure europium complex. Additionally, the magnetic properties of Fe3O4 NPs and the composite microfibers were investigated. The saturation magnetization of the composite microfibers was smaller than that of pure Fe3O4 NPs. 关键词 KeyWords Plus  HOTOLUMINESCENCE PROPERTIES; OPTICAL-PROPERTIES; NANOCOMPOSITES; NANOFIBERS作者信息 通讯作者地址: Luoyang Institute of Science & Technology Luoyang Inst Sci & Technol, Dept Math & Phys, Luoyang 471023, Peoples R China. 通讯作者地址: Liu, LN (通讯作者) 显示更多 Luoyang Inst Sci & Technol, Dept Math & Phys, Luoyang 471023, Peoples R China. 地址: 显示更多 [ 1 ] Luoyang Inst Sci & Technol, Dept Math & Phys, Luoyang 471023, Peoples R China 电子邮件地址:liuln448@163.com 基金资助致谢 基金资助机构显示详情 授权号 National Natural Science Foundation of China (NSFC) 51802139 11905096 51801092 Natural Science Foundation of Henan Province 18B140007 20B140009 19A430020 21A140016 查看基金资助信息 出版商 SPRINGER, VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS 类别 / 分类 研究方向:Engineering; Materials Science; Physics Web of Science 类别:Engineering, Electrical & Electronic; Materials Science, Multidisciplinary; Physics, Applied; Physics, Condensed Matter 文献信息 语言:English 入藏号: WOS:000666833300006 ISSN: 0957-4522 eISSN: 1573-482X 其他信息 IDS 号: TQ6BH Web of Science 核心合集中的 "引用的参考文献": 36 Web of Science 核心合集中的 "被引频次": 0 查看较少数据字段 |
