英文摘要	The uniform 1D nano-rods of RE3+doped Ln7O6F9(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)1.69F1.31using the Fourier transform infrared spectrum (FT-IR), thermal gravimetric and differential scanning calorimetry (TG-DSC). The average lengths of Y7O6F9and Lu7O6F9were about 6.8 and 7.9 μm, 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 Y7O6F9and Lu7O6F9, respectively. Upon ultraviolet excitation, Pr3+, Sm3+and Eu3+ions in Ln7O6F9showed blue, orange and red emissions originating from their characteristic f-f transitions. In addition, the 4f15d1 → 4f2band emissions (340–450 nm) as well as typical 4f2 → 4f2line emissions (450–700 nm) of Pr3+were observed in Pr3+-doped Ln7O6F9. For Sm3+-doped Ln7O6F9, 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 Ln7O6F9. © 2016 Elsevier B.V.
