摘　　要：采用高温固相法制备了稀土掺杂Sr_5(PO_4)_2SiO_4发光材料,研究了样品的发光性能,研究了预烧结温度、烧结温度、烧结时间对样品发光性能的影响。Sr_(4.975)(PO_4)_2SiO_4∶0.025Eu^(2+)荧光粉能够被400 nm左右的近紫外光激发,发射光谱受基质晶格结构影响呈现双峰发射现象。实验结果表明,预烧结温度选择850℃,烧结温度选择1400℃,烧结时间选择600 min,制得的样品的发光性能最佳。Sr5 （ P04 ） 2 Si04 luminescence material doped with rare earth was prepared by solid-state reaction method. The luminescence property of sample was investigated. Effects of the presintering temperature, sintering temperature and sintering time on the luminescence properties were explored.Sr4 975 （P04）2Si04-0. 025Eu2＋ can be well activated under UVLED about 400 nm. The phenomenon of double emission peak in the emission spectra were influenced by the matrix lattice structure. The results indicate that the best luminescence property can be obtained when presintering temperature is 850 Tl , sintering temperature is 1400 and sintering time is 600 min.
