在一氧化碳还原气氛下，通过高温固相法合成了YAG：Ce3+，Pr3+黄色荧光粉。研究Pr3+的掺杂浓度（x）与助熔剂对该荧光粉光学性能的影响，实验结果表明：当Pr3+的掺杂浓度x≤0.012时，光谱强度随x增大而增强；当x>0.012时，光谱强度随x增大而减弱。同时还发现光谱的峰值和峰形不受x的影响，主激发峰位于468nm，发射峰位于530nm和610nm。在YAG：Ce3+荧光粉中掺杂Pr3+增加了荧光粉的红色成分。AlF3做助熔剂时，可以提高荧光粉的发光性能。

The YAG:Ce3+,Pr3+ yellow phosphors were synthesized by high-temperature solid state reaction method un-der carbon monoxide reducing atmosphere. The influence of the doping concentration of Pr3+ ion and fluxing agent on phosphor’s properties was analyzed. The experimental results indicate that the intensity of spectra increases with the concentration (x) of Pr3+ ion when x is less than0.012, the intensity of spectra decreases with the increase of x when x is more than 0.012. It is also found that the parameters such as x do not affect the peak shape and peak locations, the main excitation peak locates at 473nm and the main emission peak locates at 538nm and 610nm. The red compo-nent and color rendition of YAG:Ce3+ phosphor were increased with the doping of Pr3+.The luminescent properties were improved with AlF3 as fluxing agent.
