SrAl2O4:Eu2+,Dy3+-polyethylene terephthalate (PET)/light conversion agent-PET, which is a new skin–core structure luminous fiber that can emit red light in the darkness, was fabricated by melt spinning with the combination of light conversion agent-PET and SrAl2O4:Eu2+,Dy3+-PET. An energy transfer occurred between SrAl2O4:Eu2+,Dy3+ and light conversion agent, and the light conversion agent emitted red light absorbed from SrAl2O4:Eu2+,Dy3+. To investigate the effect of light conversion agent on the luminous properties of SrAl2O4:Eu2+,Dy3+-PET-light conversion agent, several kinds of luminous fiber that contained different light conversion agents were artificially manufactured and their luminous properties were investigated. Results showed that under near-ultraviolet excitation, the fluorescent color of luminous fiber was primarily located in the orange-red area, with more intense red color than the others.
