- Abstract
Novel magnetic-photoluminescent bifunctional [FeO@YO:Eu]/polymethyl methacrylate (PMMA) flexible composite nanobelts were successfully prepared by electrospinning via dispersing FeO@YO:Eu core-shell structured nanoparticles (NPs) into the PMMA matrix. The morphology, structure and properties of the flexible composite nanobelts were investigated by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, vibrating sample magnetometry and fluorescence spectroscopy. The width and thickness of [FeO@YO:Eu]/PMMA composite nanobelts are 3.58 ± 0.29 and 1.2 μm, respectively. Fluorescence emission peaks of Eu in [FeO@YO:Eu]/PMMA flexible composite nanobelts are observed and assigned to the energy levels transitions of D → F (580 nm), D → F (533, 586, 592, 599 nm), D → F (612 nm) and D → F (629 nm) of Eu ions. Compared with FeO/YO:Eu/PMMA nanobelts, [FeO@YO:Eu]/PMMA flexible composite nanobelts possess much stronger luminescent intensity. The as-prepared flexible composite nanobelts exhibit excellent magnetism and photoluminescent performance. The intensities of magnetism and luminescence of the flexible composite nanobelts can be simultaneously tuned by adjusting the amount of FeO@YO:Eu NPs introduced into the nanobelts. The high performance [FeO@YO:Eu]/PMMA flexible composite nanobelts have potential applications in the fields of cell separation, magnetic resonance imaging, drug deliver and future nanodevices.
