Fabrication and Luminescent Properties of Eu³+ Doped Lanthanide Oxide Nanowires and Nanotubes by Electrospinning

This paper described a novel approach for preparing singly-distributed 1D nanostructures of Y₂O₃, YVO₄ and YBO₃ doped with europium by electrospinning. The morphology and the crystal structure were investigated by SEM, TEM, and XRD. The luminescence properties of the 1D lanthanide oxide nanostructures were also characterized. These nanowires and nanotubes exhibited good luminescent properties. The fluorescence lifetimes ⁵D₀ level for Eu³⁺ in Y₂O₃:Eu nanowires and YVO₄:Eu nanowires and YBO₃:Eu nanotubes were determined to be 560 mus and 493 mus and 1.63 ms, respectively. These nanowires and nanotubes will be probably applicable to make photovoltaic devices, solar cell and other photoelectric devices.
