摘要

Large-scale Y_2O_3:Eu nanotubes have been successfully fabricated by an improved sol-gel method within the nanochannels of porous anodic alumina templates. In this method, yttrium nitrate, europium nitrate and urea were used as precursors, yttrium nitrate and europium nitrate were acting as sources of europium and yttrium ions, and urea offered a basic medium through its hydrolysis. X-ray diffraction techniques, scanning electron microscopy, transmission electron microscopy and selected-area electron diffraction were used to characterize the Y_2O_3:Eu nanotubes obtained. It is found that the prepared Y_2O_3:Eu nanotubes can be indexed as a polycrystalline cubic structure and their outer diameters are about 50-80 nm, with the thickness of the tube wall estimated to be around 5 um. The emission peaks of the as-prepared Y_2O_3 Eu nanotubes are broader than those of bulk Y_2O_3 Eu because of the disordering of the crystal phase possibly induced by the increase of the surface/volume ratio in the nanotubes.
