採用高溫固相法製備長餘輝發光材料SrAbO4:Eu2+, Dy3+，通過熔融紡絲法製備稀土夜光纖維。 採用X射線粉末衍射、激發光譜、發射光譜對樣品進行表徵，研究光轉換劑對夜光纖維發光 性能的影響。結果表明：光轉換劑的摻入沒有引起SrAl2O4:Eu2+, Dy3+的晶體結構的變化，但對 發射光譜有著顯著影響。隨著光轉換劑的增多，520 nm處的發射峰強度逐漸降低，580 nm左 右的發射峰強度逐漸增大，當光轉換劑含量為7%時其發射強度達到最大，隨後繼續增加，發 射強度反而下降且發射光譜向長波方向移動。稀土夜光纖維內部存在SrAl2O4:Eu2+, Dy3+向光轉 換劑能量傳遞。

SrAbO4:Eu2+, Dy3+ was fabricated by means of solid-state reaction and rare earth luminous fiber was prepared by method of melt spinning. X-ray diffraction (XRD) and fluorescence spectrophotometer were used to characterize the resulting samples. Results from XRD and fluorescence spectrophotometer demonstrated that the phase of SrAhO4: Eu2+, Dy3+ in the fiber was not destroyed in the manufacturing process, but it had great effect on the emission spectra. As light conversion agent increased, emission intensity of 520 nm decreased gradually, and emission peak intensity of 580 nm gradually increased. When the light conversion agent content was 7%, the intensity of the emission reached the maximum, and then decreased when continuing to increase, and the emission spectra shifted to longer wavelengths. And there was energy transfer from SrA12O4: Eu2+, Dy3+ to light conversion agent used in the luminous fiber.
