Abstract：Bouquet-shaped, spindle, nanobundle and truncated octahedral YF3:Eu3＋nanomaterials were prepared using surfactant-assisted hydrothermal method, the properties and structure were characterized. XRD pattern showed that the samples are all orthogonal phase YF3 with good crystallization. FESEM and TEM images indicated that the samples with different morphologies are obtained by different surfactants. SEAD photoes showed that the samples are polycrystalline and single crystal, EDX pattern showed that the samples are composed by F, Y and Eu elements. Photoluminescence spectra showed that the strongest emission peak of YF3:Eu3＋ nanocrystals is near 591 nm, corresponding to 5D0-7F1 magnetic dipole transition of Eu3＋, which indicated that Eu3＋ is sited in C2-symmetric site of Y3＋ lattice point in YF3 host, and it is noted that the emission intensities are different from samples with different morphologies.
