Abstract

One-dimensional SrAl(2)O(4):Eu(2+), Dy(3+) fibers were fabricated by a simple electrospinning combined with sol-gel process. X-ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, transmission electron microscopy and photoluminescence were used to characterize the fibers. The results show that the phase structure of SrAl(2)O(4):Eu(2+), Dy(3+) belongs to a monoclinic one, the composite fibers and fibers calcined at high temperature remain the original one-dimensional texture, and the SrAl(2)O(4):Eu(2+), Dy(3+) was a green emission.
