“…The excitation spectra ( Figure 4A, 4B) consist of a broad excitation band extending from 200 to 350 nm with a maximum at 281 nm in the wavelength region, which is attributed to the π→π* electron transition of the conjugated double bonds of the ligand. The excitation intensity is 20 increased with introducing more Tb(BA) 3 phen when monitored at 545 nm ( Figure 4A), while the excitation intensity is increased with the increase of Eu 3+ ion concentration ( Figure 4B) when the monitoring wavelength is 615 nm. It offers an approach to tune emission colors by adjusting the mass ratio of Eu(BA) 3 phen to Tb(BA) 3 …”

“…Moreover, belt-shaped cables have better anti-entangling performance and smaller winding volume, and they have higher electrical conduction than the traditional fibers with the same components. Inspired by the structure of microcable, in this work, 20 we designed and fabricated novel belt-shaped coaxial microcable composed of a Fe 3 O 4 NPs/PANI/polymethyl methacrylate (PMMA) core and a RE (RE= Eu, Tb) complexes/PMMA shell. By constructing such kind of structure, luminescent compounds can be effectively isolated from Fe 3 O 4 NPs and PANI to avoid 25 direct contact.…”

“…Excitation spectra (A, B), emission spectrum (C) of belt-shaped coaxial microcables containing different mass percentages of PANI and UV-Vis absorbance spectrum of PANI/PMMA (D).The CIE chromaticity coordinates for the samples and their20 corresponding photographs upon excitation at 281-nm ultraviolet light are provided in theFigure 9. It demonstrates that the emitting color of belt-shaped coaxial microcables becomes more green with introducing more PANI, due to the stronger absorption of red light by PANI.…”

A novel type of flexible [Fe3O4/PANI/PMMA]@{[Eu(BA)3phen + Tb(BA)3phen]/PMMA} (PMMA = polymethyl methacrylate, BA = benzoic acid, phen = phenanthroline, PANI = polyaniline) belt-shaped coaxial microcable possessing electrical conductivity, magnetism and color-tunable photoluminescence has been successfully fabricated by electrospinning technology using a specially designed coaxial spinneret. Every strip of belt-shaped coaxial microcable is assembled with a Fe3O4/PANI/PMMA electrically conductive -magnetic bifunctional core and a [Eu(BA)3phen + Tb(BA)3phen]/PMMA insulative and photoluminescence-tunable shell. The conductivity of the core of belt-shaped coaxial microcables reaches up to the order of 10(-2) S cm(-1) and all belt-shaped coaxial microcables are insulated from each other. The tuning of emission color is possible by changing the Eu(3+)/Tb(3+) molar ratio of the belt-shaped coaxial microcables. The electrical conductivity, magnetic and photoluminescence properties of belt-shaped coaxial microcables can be tuned by adjusting the content of PANI, Fe3O4 nanoparticles (NPs) and rare earth complexes. More importantly, the proposed design idea and the construction technique are universal regarding the preparation of other multifunctional one-dimensional micromaterials.

“…Electrospinning is a simple and effective method to fabricate one-dimensional micro-and nanomaterials, such as nanofibers [26,27], hollow nanofibers [28,29], coreshell structured coaxial nanofibers [30,31] and nanobelts [32,33]. However, to the best of our knowledge, there have been no reports on the preparation of rare earth oxysulfides hollow nanofibers by electrospinning combined with sulfurization technique in the literatures.…”

Y 2 O 3 :Eu 3? hollow nanofibers were prepared by calcination of the electrospun PVP/[Y(NO 3 ) 3 ? Eu(NO 3 ) 3 ] composite nanofibers, and then Y 2 O 2 S:Eu 3? hollow nanofibers were successfully synthesized by sulfurization of the as-obtained Y 2 O 3 :Eu 3? hollow nanofibers via a double-crucible method using sulfur powders as sulfur source. The samples were investigated in detail by X-ray diffractometry (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy, and fluorescence spectroscopy. XRD analysis shows that the Y 2 O 2 S:Eu 3? hollow nanofibers are pure hexagonal phase with the space group of P " 3m1. SEM observation indicates that as-prepared Y 2 O 2 S:Eu 3? nanofibers are obvious hollowcentered structure with the mean outer diameter of 184 ± 26 nm. Under the excitation of 260-nm ultraviolet light, the Y 2 O 2 S:Eu 3? hollow nanofibers exhibit red emissions of predominant emission peaks at 628 and 618 nm originated from 5 D 0 ? 7 F 2 energy levels transitions of Eu 3? ions. The luminescent intensity of Y 2 O 2 S:Eu 3? hollow nanofibers is remarkably increased with the increase of doping concentration of Eu 3? ions and reaches a maximum at 3 mol % of Eu 3? ions. The emitting colors of the samples are located in the red region in CIE chromaticity coordinates diagram. The possible formation mechanism of Y 2 O 2 S:Eu 3? hollow nanofibers is also proposed. This preparation technique could be applied to prepare other rare earth oxysulfide hollow nanofibers.

In order to develop new-typed multifunctional nanocomposites, fluorescent-electrical-magnetic trifunctional coaxial nanoribbons with tunable fluorescent color, including white-light emission, have been successfully fabricated via coaxial electrospinning technology. Each stripe of coaxial nanoribbon is composed of a Fe3O4/PMMA core and a [Eu(BA)3phen+Dy(BA)3phen]/PANI/PMMA (PMMA = polymethyl methacrylate, BA = benzoic acid, phen = phenanthroline, polyaniline = PANI) shell. X-ray diffractometry (XRD), field emission scanning electron microscopy (FE-SEM), biological microscopy (BM), vibrating sample magnetometry (VSM), energy dispersive spectrometry (EDS), Hall effect measurement system and photoluminescence (PL) spectroscopy were employed to characterize the coaxial nanoribbons. Emitting color of the coaxial nanoribbons can be tuned by adjusting the contents of Dy(BA)3phen, Eu(BA)3phen, PANI and Fe3O4 in a wide color range of blue-white-orange under the excitation of 273-nm single-wavelength ultraviolet light. The coaxial nanoribbons simultaneously possess excellent luminescent performance, electrical conduction and magnetism compared with the counterpart composite nanoribbons. Furthermore, the electrical and magnetic performances of the coaxial nanoribbons also can be tunable by adding different quantities of PANI and Fe3O4 nanoparticles, respectively. The obtained coaxial nanoribbons have promising applications in many areas, such as electromagnetic interference shielding, microwave absorption, molecular electronics, biomedicine, future nanomechanics and display fields.
