Abstract:
In the present paper, we reported the successful synthesis of dumbbell-like YF(3) nanostructures with a high yield in a mixed system of water/N,N-dimethylformamide (DMF) under the assistance of ultrasound waves of 40kHz with the ultrasonic power of 100% (200W) at 65 degrees C for 2h, employing Y(2)O(3) (99.99%) and NH(4)F as the starting reactants. The product was characterized by means of powder X-ray diffraction (XRD), energy dispersive spectrometry (EDS), transmission electron microscopy (TEM), selected area electron diffraction (SAED) pattern and field-emission scanning electron microscopy (SEM). Some factors influencing the morphology of YF(3) nanostructures, including the ultrasonic time and power, the amount of NH(4)F, and the ratio of water/DMF, were systematically investigated. Research showed that the morphology of YF(3) could be tuned by the volume ratio of water/DMF. The roles of DMF and the ultrasonic wave in the formation of YF(3) nanostructures were discussed.
