Abstract
One-dimensional Y2Ti2O7:Ho/Yb nanostructures, including nanowires, nanotubes, and wire-in-tube architectures, were fabricated via a simple electrospinning technique using a single-nozzle system. The diameters of Y2Ti2O7:Ho/Yb nanowires are between 180 and 200 nm. The Y2Ti2O7:Ho/Yb nanotubes have an outer diameter of 180 nm and a wall thickness of 30–40 nm. In the Y2Ti2O7:Ho/Yb wire-in-tube architectures, the outer diameter of tubes, wall thickness of tubes, and diameter of wire are 180–190, 25–30, and 30–35 nm, respectively. The electrospinning process's environment humidity considerably influences the one-dimensional Y2Ti2O7:Ho/Yb nanostructure morphology. Further, the upconversion luminescence properties and temperature sensitivity of the one-dimensional Y2Ti2O7:Ho/Yb nanostructure were investigated compared with that of the Y2Ti2O7: Ho/Yb bulk prepared via solid-state reactions. Furthermore, to realize their dual-mode anticounterfeiting function, the Y2Ti2O7:Ho/Yb nanotubes were coated with a rare-earth nitrate (RE (NO3)3) using a homogeneous precipitation technique to obtain core-shell structure nanotubes of Y2Ti2O7:1 mol%Ho/20 mol%Yb @ Y2O3:10 mol%Eu.
