| 英文摘要 | The uniform 1D nano-rods of RE3+ doped Ln(7)O(6)F(9) (Ln = Y and Lu; RE = Pr, Sm and Eu) were synthesized through a facile two-step hydrothermal method without extra fluorine source followed by post-heat treatment. The phase formation, morphologies, as well as photoluminescence properties of the materials were investigated. The precursor composition was determined to be Ln(OH)(1.69)F-1.31 using the Fourier transform infrared spectrum (FT-IR), thermal gravimetric and differential scanning calorimetry (TG-DSC). The average lengths of Y7O6F9 and Lu7O6F9 were about 6.8 and 7.9 mu m, respectively, with the average width of about 650 nm. It was interesting that the tip of the nano-rods exhibits a straight line and divergent umbrella shaped bifurcation for Y7O6F9 and Lu7O6F9, respectively. Upon ultraviolet excitation, Pr3+, Sm3+ and Eu3+ ions in Ln(7)O(6)F(9) showed blue, orange and red emissions originating from their characteristic f-f transitions. In addition, the 4f (1)5d(1) -> 4f(2) band emissions (340-450 nm) as well as typical 4f(2) -> 4f(2) line emissions (450-700 nm) of Pr3+ were observed in Pr3+-doped Ln(7)O(6)F(9). For Sm3+-doped Ln(7)O(6)F(9), only the typical f - f transitions of Sm3+ were observed with the absence of charge transfer (CT) band. However, the broad excitation bands at 255 nm attributing to the charge transfer transition of Eu3+ (i.e. O2- -> Eu3+ CT) were observed in Eu3+-doped Ln(7)O(6)F(9). (C) 2016 Elsevier B.V.
