摘　　要：在CTAB辅助的水热条件下制备出YF3:Eu3+纳米束材料。XRD分析表明:样品为结晶良好的正交相YF3。TEM照片表明:所得样品直径为250nm,长度约为1000nm的YF3:Eu3+纳米束,且纳米束是由直径为20nm,长度为100nm的纳米晶自组装而成。SEAD显示所得样品为单晶结构。光谱测试表明样品的最强发射峰位于591nm处,为Eu3+的特征橙红光发射,对应Eu3+的5D0→7F1的磁偶极跃迁。YF3：Eu^3＋ nanobundles were prepared using CTAB-assisted hydrothermal method.XRD patterns showed that the samples are orthogonal phase YF3 with good crystallization.TEM images presented that the samples are homogeneous nanobundles with a diameter of 250 nm and a length of 1000 nm,which are self-assemblied by nanocrystals with a diameter of 20 nm and a length of 100 nm.SEAD image showed that the samples are single crystal.Photoluminescence spectra showed that the strongest peak is near 591 nm,which emits characteristic orange-red light of Eu^3＋, corresponding to ^5D0→^7F1 magetic dipole transition of Eu^3＋.
