报告英文简介：

Rare earth luminous fiber was prepared by method of melt spinning. X-ray diffraction (XRD), scanning electron microscopy (SEM), and fluorescence spectrophotometer as well as afterglow brightness tester were used to characterize the resulting samples. Results from XRD and SEM demonstrated that the phase of SrA12O4: Eu2+, Dy3+ in the fiber was not destroyed in the manufacturing process and the as-formed luminous fiber consisted of irregular particles. Under ultraviolet excitation, the luminous fiber exhibited a yellow-green and orange-red emission band with a maximum at 520 nm and around 600 nm originating from SrAl2O4:Eu2+,Dy3+ and red organic fluorescent pigments. The energy transfer process was further studied. Furthermore, the emission colors of luminous fibers can be tuned from yellow-green to orange-red easily by doping red organic fluorescent pigment, making the materials have potential application in many areas.
