Abstract
New nanostructures betokening new nanotechnology and nanoscience. In this work, novel one-dimensional (1D) Y2(Zr0.6Ti0.4)2O7:Eu tube-in-tube nanostructures were fabricated by a simple single-nozzle electrospinning method. The Y2(Zr0.6Ti0.4)2O7:Eu double-layered nanotube consisted of an outer tube with a diameter of 250–340 nm and an inner tube with a diameter of 80–110 nm. The wall thickness of the outer tube is ∼30 nm. The wall thickness of the inner tube is ∼25 nm. The key to this technique is to utilize the difference in hydrolysis rates between the titanium source and the zirconium source in an air atmosphere with a humidity of 40–45% to obtain nanoscale tube-in-tube structures. The Y2(Zr0.6Ti0.4)2O7:Eu tube-in-tube nanostructures exhibit excellent luminescence stability and lower color drift performance at high temperatures.
