摘　　要：目的:探索高效生物标记纳米荧光材料制备方法。方法:采用水热法合成了Gd x Y0.98-x F3:Eu3+0.02(x=0~0.98)纳米材料;通过XRD、TEM和荧光光谱对样品进行结构、形貌和性能表征;研究了Gd3+浓度对Eu3+发光性能的影响。结果:材料的晶体结构和发光性能随x变化而改变。其中,Gd0.6Y0.38F3:Eu3+0.02在直接激发和Gd0.7Y0.28F3:Eu3+0.02在基质激发时均可获最强发光。结论:Gd x Y0.98-x F3:Eu3+0.02有望成为一种可实现生物标记的红色纳米荧光探针。Objective：To explore the method of preparing luminescent nanomaterials for efficient biolabels. Methods：GdxY0.98-xF3：Eu0.023＋ nanomatenals Were prepared by hydrothermal synthesis. The structure, morphology and property of samples were charactered by XRD, TEM and fluorescence spectrophotometer. The effects of Gd3＋ concentrations on l properties of Eu3＋ were investiga- ted. Results：Crystal structure and luminescence property of samples are changed with increasing x values. The integrated intensities of nanomaterials have great potential to be one luminescence reach up to maximum when x is 0. 6 or 0. 7. Conclusion： GdxY0.98-xF3：Eu0.023＋ of red efficient fluorescence biolabels in future.
