Due to the low earth fluoride phonon energy , is a kind of highly efficient rare earth ion doped luminescent substrate , in medical testing , security , lighting , display and other fields have a wide application prospects. Currently rare earth fluoride nanomaterials research focuses on nanoparticles , nanorods and nanotubes aspects . In order to study its various properties , the urgent need for a preparation of rare earth fluoride nanofibers and nanoribbons method . Electrospinning method in the preparation of one-dimensional nanomaterials has simple operation, good repeatability , etc., to be the best choice. Therefore , the use of electrostatic spinning method nanofibers and nanoribbons fluoride is an important research topic interesting . This paper studied the electrospinning technology to prepare nanomaterials with different morphologies of the PVP , the first solution is drawn between parameters and product morphology diagram and apply experimental design . In this figure , under the guidance prepared for further use as a template out of the PVP nanofibers and nanoribbons , Y2O3: Eu3 nanofibers and nanoribbons . In yttrium fluoride nanomaterials , based on the first obtained by controlling the calcination temperature YF3: Eu3 nanofibers , YOF: Eu3 nanofibers and nanoribbons and Y7O6F9: Eu3 nanoribbons and studied the luminescence properties of these nanomaterials . By Y7O6F9: Tb3 other modern materials test and analysis techniques , the prepared samples were analyzed systematically . The results show that the original fiber obtained after calcination at 700 ℃ cubic phase XRD, FTIR, SEM, TEM, PL nano material, after NH4HF2 fluorinated obtain orthorhombic YF3: Eu3 nano-materials , and then calcined 9h 580 ℃ obtain orthorhombic Y2O3: Eu3 nano-materials, calcined at 700 ℃ for 9h get rhombohedral Y7O6F9: Eu3 Nemi material . The diameter of the nano fibers 70-200nm. Nm band width of 3-10μm, the thickness of YOF: Eu3 (?) 80-200 nm. YOF: Eu3 and Y7O6F9: Eu3 nanomaterials strongest emission peaks are 5D0 → 7F2 transition , and Y2O3: Eu3 (?) Within meters of materials strongest emission peak 5Do → 7F1 transition . Which , Y7O6F9: Eu3 strongest luminescence nanomaterials .
