Electrospinning fabrication and properties of Fe3O4/Eu(BA)3phen/PMMA magnetic–photoluminescent bifunctional composite nanoribbons

A new type of magnetic–photoluminescent bifunctional Fe3O4/Eu(BA)3phen/PMMA composite nanoribbons was successfully prepared. The average width of the composite nanoribbons was ca. 19.05 ± 1.83 μm, and the thickness was ca. 786 nm. Fluorescence emission peaks of Eu3+ were observed in the Fe3O4/Eu(BA)3phen/PMMA composite nanoribbons. The factors effecting fluorescence intensity were researched via adding different ratios of Eu(BA)3phen to PMMA and Fe3O4 nanoparticles to PMMA. The fluorescent spectra demonstrated that the optimum weight percentage of Eu(BA)3phen to PMMA was 10% due to the concentration quenching effect. Saturation magnetization of the composite nanoribbons was enhanced through introduction of more Fe3O4 nanoparticles, but the fluorescence intensity of the composite nanoribbons was decrease.

► Fe3O4/Eu(BA)3phen/PMMA composite nanoribbons were prepared by electrospinning.
► The products possess magnetic–photoluminescent bifunction.
► The composite nanoribbons have large width to thickness ratio and large length.
► The optimum mass percentage of Eu(BA)3phen to PMMA was 10%.
► The fluorescence and saturation magnetic intensities of the products can be tuned.
