Flexible Janus nanoribbons to help obtain simultaneous color-tunable enhanced photoluminescence, magnetism and electrical conduction trifunctionality

Abstract

Upon the unique feature of the asymmetry dual-sided Janus structure, the strong luminescence of the luminescent–electrical–magnetic Janus nanoribbons can be achieved.

A review on electrospun magnetic nanomaterials: methods, properties and applications

“…This technology has been utilised to produce materials with superior properties in catalysis, sensing, biomedicine and display technology. [27][28][29][30] 2.1.2.4 Collecting methods and collectors. In addition to nozzle design, and the whip and curing stages of the electrospinning process, the overall morphology of the fibre can be controlled by changing the method of collection.…”

Novel nanofiber yarns synchronously endued with tri-functional performance of superparamagnetism, electrical conductivity and enhanced fluorescence prepared by conjugate electrospinning

“…It is already known that absorption by Fe 3 O 4 NPs in ultraviolet light (where the wavelength is less than 400 nm) is much easier than in visible light (where the wavelength ranges from 400 to 760 nm), and that PANI strongly absorbs light in the region of 400-760 nm. 47 Thus, Fe 3 O 4 NPs and PANI can absorb the excitation light (281 nm) and emission light (580, 593 and 616 nm) of the heterogeneous nanober yarns. Furthermore, the more Fe 3 O 4 NPs and PANI introduced into the yarns, the stronger the light absorption by the Fe 3 O 4 NPs and PANI is, and the darker the color of the samples and the weaker the emitting light from the samples are, which can also be seen in Fig.…”

Pseudo-tricolor typed nanobelts and arrays simultaneously endowed with conductive anisotropy, magnetism and white fluorescence

“…However, if the fluorescent materials are too closely connected, they will interact with each other, so ET between the two fluorescent materials will occur. 35 Previous studies 36–42 have demonstrated that when dark-colored conductive and magnetic materials are straightly in contact with fluorescent materials, the fluorescence intensity of fluorescent materials will be significantly reduced. For one thing, the dark-colored conductive and magnetic materials can absorb visible light (400–700 nm) and much more easily absorb ultraviolet light (<400 nm).…”
