“…Along similar lines, Y 2 Ti 2 O 7 :Tm 3+ /Yb 3+ nanoparticles were electrospun into nanofibers which, on irradiation with 980 nm laser, showed prominent emissions at 480, 656, 689, and 803 nm assigned to the Tm 3+ transitions of 1 G 4

Electrospun nanofibers possess a large surface area and a three-dimensional porous network that makes them a perfect material for embedding functional nanoparticles for diverse applications. Herein, we report the trends in embedding upconversion nanoparticles (UCNPs) in polymeric nanofibers for making an advanced miniaturized (bio)analytical device. UCNPs have the benefits of several optical properties, like near-infrared excitation, anti-Stokes emission over a wide range from UV to NIR, narrow emission bands, an extended lifespan, and photostability. The luminescence of UCNPs can be regulated using different lanthanide elements and can be used for sensing and tracking physical processes in biological systems. We foresee that a UCNP-based nanofiber sensing platform will open opportunities in developing cost-effective, miniaturized, portable and user-friendly point-of-care sensing device for monitoring (bio)analytical processes. Major challenges in developing microfluidic (bio)analytical systems based on UCNPs@nanofibers have been reviewed and presented.

“…Upon excitation at 980 nm, the UCNP showed strong upconversion emission around 550 nm [ 124 ]. Other examples of the use of upconverting nanoparticles in electrospun nanofibres include the incorporation of Y 2 Ti 2 O 7 :Tm/Yb UCNPs in PVP [ 125 ] and Bi 2 Ti 2 O 7 :Tm 3+ /Yb 3+ in PVP [ 126 ].…”

Electrospinning is a cost-effective and efficient method of producing polymeric nanofibre films. The resulting nanofibres can be produced in a variety of structures, including monoaxial, coaxial (core@shell), and Janus (side-by-side). The resulting fibres can also act as a matrix for various light-harvesting components such as dye molecules, nanoparticles, and quantum dots. The addition of these light-harvesting materials allows for various photo-driven processes to occur within the films. This review discusses the process of electrospinning as well as the effect of spinning parameters on resulting fibres. Building on this, we discuss energy transfer processes that have been explored in nanofibre films, such as Förster resonance energy transfer (FRET), metal-enhanced fluorescence (MEF), and upconversion. A charge transfer process, photoinduced electron transfer (PET), is also discussed. This review highlights various candidate molecules that have been used for photo-responsive processes in electrospun films.

“…In our previous works, Y 2 Ti 2 O 7 nanowires, nanotubes and nanowire-embedded nanotube nanostructures were synthesized by a simple single-nozzle electrospinning method. 24,25 Here, we developed this single-nozzle electrospinning technique to fabricate 1D Y 2 (Zr 0.6 Ti 0.4 ) 2 O 7 :Eu tube-in-tube nanostructures using the difference in hydrolysis rates between the titanium source and the zirconium source in a moist air atmosphere to fabricate 1D Y 2 (Zr 0.6 Ti 0.4 ) 2 O 7 :Eu tube-in-tube nanostructures. The obtained Y 2 (Zr 0.6 Ti 0.4 ) 2 O 7 : Eu tube-in-tube nanostructures consisted of an outer tube with a diameter of 250-340 nm and an inner tube with a diameter of 80-110 nm.…”
