以低温燃烧合成法制备了BaxNayYzF2x+y+3z+3m∶Er3+m上转换荧光粉, 通过X射线衍射仪和扫描式电子显微镜对荧光粉的物相及形貌进行分析, 采用正交实验法得出最佳配方。通过测试Er3+和Y3+掺杂浓度不同的样品的上转换发光性能, 研究了掺杂浓度对红绿光上转换的影响。结果表明：增大Y3+的掺杂浓度, 有利于绿光上转换过程; 增大Er3+的掺杂浓度, 有利于红光上转换过程。

Up-conversion phosphor BaxNayYzF2x+y+3z+3m∶Er3+m is synthesized by low-temperature combustion synthesis method. The phase and morphology of the phosphor are analyzed by X-ray diffraction and scanning electron microscopy, and the optimal formula is obtained by orthogonal experiment. The effects of doping concentration of Er3+ and Y3+ ions on green and red up-conversion is studied by measuring the up-conversion luminescence property of samples with different doping concentrations. The results show that increasing the doping concentration of Y3+ ion is beneficial to green up-conversion luminescence, increasing the doping concentration of Er3+ ion is beneficial to red up-conversion luminescence.
