摘 要：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 could be tuned from yellow-green to orange-red easily by doping red organic fluorescent pigment,making the materials have potential application in many areas.
