Abstract:
Y 2 O 3 :Eu 3+ nanoparticles (NPs), polyaniline (PANI), and Fe 3 O 4 NPs are incorporated into polymethyl methacrylate (PMMA) and electrospun into [Y 2 O 3 :Eu 3+ /PMMA]//[PANI/Fe 3 O 4 /PMMA] Janus nanobelts with Y 2 O 3 :Eu 3+ /PMMA as one half side and PANI/Fe 3 O 4 /PMMA as the other. The morphology and properties of the final products are investigated in detail by X‐ray diffraction (XRD), scanning electron microscopy (SEM), optical microscopy (OM), energy‐dispersive spectrometry (EDS), Hall effect measurements, fluorescence spectroscopy, vibrating sample magnetometry (VSM), and UV/Vis spectroscopy. The results reveal that the [Y 2 O 3 :Eu 3+ /PMMA]//[PANI/Fe 3 O 4 /PMMA] trifunctional Janus nanobelts possess excellent electrical conductivity, magnetism, and fluorescence owing to their special nanostructure. Fluorescence emission peaks of Eu 3+ are observed in the Janus nanobelts. The electrical conductivity reaches the order of 10 −4 S cm −1 . The luminescent intensity, electrical conductivity, and saturation magnetization of the Janus nanobelts can be tuned by adjusting the respective amounts of Y 2 O 3 :Eu 3+ NPs, PANI, and Fe 3 O 4 NPs. The flexible luminescent‐electrical‐magnetic trifunctional Janus nanobelts have many potential applications. More importantly, this design concept and construct technology is of universal significance for the fabrication of other multifunctional nanostructures.
