摘要：
Cerium doped yttrium aluminium garnet (YAG:Ce) nanofibers were prepared by electrospinning technique. The microstructure and morphology of electrospun nanofibers were studied by scanning electron microscope, and the luminescence properties of YAG:Ce electrospun nanofibers were investigated by luminescence spectrophotometer. When the as-prepared YAG:Ce electrospun nanofibers were calcined under reducing atmosphere, a layer of protuberant spheres with the diameter of 50-100 nm grew on the surface of YAG:Ce electrospun nanofibers. The emission intensity of the electrospun YAG:Ce nanofibers heat-treated under reducing atmosphere was stronger than that prepared in air. The emission of electrospun YAG:Ce nanofibers showed a red-shift with increasing Ce3+ concentration.
