Abstract

CeF3 nanocrystals were successfully synthesized via ultrasound assisted route, which were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), powder Xray diffraction (XRD), ultraviolet (UV) spectroscope and photoluminescence spectrophotometer (PL). The results show that the shape and size of products are strongly depended on the ultrasonic time. With the increment of the ultrasonic time, the morphology of the CeF3 nanocrystals changes from “lantern” particles to uniform disklike particles. The UV absorption peak and the band-edge of the CeF3 nanocrystals exhibit a pronounced blue shift as the size of the particles decreasing, the PL intensity of CeF3 nanocrystals is related to the crystalline extent.

Key words： ultrasonicassisted; cerium fluoride nanocrystalline; characterization; ultrasonic time
