Fabrication And Characterization Of One-dimensional Rare Earth Fluorides Luminescent Nanomaterials Via Solvothermal Method

It is known that the size, shape and microstructre of inorganic nanomaterials influence their properties and applications. the synthesis and property of inorganic nanomaterials (for example, nanowires, nanorods, nanobundle) with special morphologies and microstruetures influence the research of new inorganic functional materials,too. Rare earth luminescence materials are widely used in the fields of lighting, display and detection due to the rare earth ions have special electronic shell structure. Rare earth fluorides are excellent matrixes for luminescent materials because of their diversity structural features and special physical and chemical characteristic. Therefore, it will be an important and novel research subject to prepare rare earth ions-doped rare earth fluorides nanorods via Solvothermal method and to investigate their characteristics. The samples were systematically characterized by XRD, FESEM, EDS, PL, etc. The results show that both the rare earth ions-doped rare earth fluorides nanorods possess excellent luminescent properties. Some significant results were obtained, and laid solid foundations for the future study of rare earth luminescent nanomaterials. The results were summarized as follows:1.La(OH)3:Eu3+ nanorods were prepared by Solvothermal method, LaF3:Eu3+ luminescent nanomaterials were prepared by solid phase reaction using NH4HF2.Thus, the luminescent properties are studied.2.Y(OH)3:Eu3+ nanorods were prepared by PEG-assisted Solvothermal method, YF3:Eu3+ luminescent nanomaterials were prepared by solid phase reaction using NH4HF2.Thus, the luminescent properties are studied.3.Y(OH)3:Tb3+ nanorods were prepared by Solvothermal method, YF3:Tb3+luminescent nanomaterials were prepared by solid phase reaction using NH4HF2.Thus, the luminescent properties are studied.4.Gd(OH)3:Eu3+ nanorods werepreparedby Solvothermal method, GdF3:Eu3+ lumine-scent nanomaterials were prepared by solid phase reaction using NH4HF2.Thus, the luminescent properties are studied.
