“…The possible reason for the fluorescence enhancement is that the surface properties were greatly improved after PVP coating, which prevented the formation of surface defects of GdVO 4 : Yb, Ho UCNPs thus decreasing the probability of non-radiative transition. 32 The dependency of emission intensities on power helps in identifying the number of incident photons involved in a particular upconversion transition.

“…However, the full width at half maximum (FWHM) reported previously is less than 100 nm, which seriously restricted their applications as broadband optical amplifiers and fibers. [27][28][29] Ni 2+ ions, when located in octahedrally coordinated sites, exhibit intense broadband NIR emission at 1.3 mm optical communication window. 35,36 A spinel (such as ZnAl 2 O 4 , MgAl 2 O 4 ) lattice with a space group of Fd % 3m can provide a large number of octahedral sites.…”

By finely tuning the electrospun parameters (feeding rate of solution, working voltage and distance, etc.) and concentration of inorganic salts, various ZnAl(2)O(4) nanostructures (nanoparticles, nanonecklaces, nanofibers, nanotubes and hollow micromelts) were controllably synthesized by a single-nozzle electrospinning technique. The formation mechanisms of different ZnAl(2)O(4) nanostructures, including 'oriented attachment' mechanism, 'gas-push' mechanism, etc., were proposed to elucidate the morphology of the nanostructures and microstructure evolvement process. The morphology and microstructure of calcined electrospun nanostructures were considered to be mainly dependent on two factors, i.e. concentration of inorganic salts and size of as-prepared electrospun nanofibers. Using Ni(2+) ions as activators, broadband near infrared (NIR) emission covering 1000-1400 nm peaking at about 1176 nm was detected in Ni(2+)-doped ZnAl(2)O(4) nanostructures. The broadband NIR emission at around 1.3 μm optical communication window with a long lifetime of ~640 μs makes Ni(2+)-doped ZnAl(2)O(4) nanostructures as a promising candidate for micro/nano-broadband optical amplifiers, fibers, etc.

“…To date, a number of rare earth ions, including Eu 31 , Er 31 , Nd 31 and Yb 31 , have been successfully doped into polymer solutions and fabricated into polymer nanofibers. 23,[82][83][84][85][86][87] These polymer nanofibers show improved photoluminescence and thermal properties over the pure complex. In contrast to polymer nanofibers doped with organic dyes or quantum dots, which are usually optically active only at wavelengths shorter than 1 mm, 16,22 polymer nanofibers doped with rare earth ions offer the possibility of working in the second and third communication windows (1300 and 1500 nm), 84,86 which are of great interest for telecommunication applications (e.g., optical amplifiers and lasers 88 ).…”

As an organic optical fiber with a diameter comparable to or less than the wavelength of light, polymer nanofibers have been attracting increasing attention as a platform for manipulating light at the nanoscale. A variety of applications for polymer optical nanofibers, including waveguides, light sources and sensors, have been reported in recent years. In this article, the recent progress in the field of polymer optical nanofibers is reviewed in terms of their fabrication, characterization and applications. In particular, we focus on functionalized polymer nanofibers doped with functional materials, such as dye molecules, noble metal nanoparticles, quantum dots and rare earth ions, which greatly expand their capabilities of generating, propagating, converting and modulating light at the nanoscale.
