摘　　要：Uniform lanthanide orthophosphate （LnPO4, Ln = La and Ce） nanorods were successfully synthesized by a simple ultrasonic irradiation method using lanthanide nitrate salt （Ln（NO3）3-6H2O, Ln = La and Ce） and sodium phosphate （Na3PO4） in aqueous solutions with the pH of 1-3. The products were characterized by X-ray diffraction （XRD）, scanning electron microscopy （SEM）, transmission electron microscopy （TEM）, high-resolution transmission electron microscopy （HRTEM）, Fourier transform infrared spectrometer （FT-IR）, and UV-visible （UV-Vis） spectroscopy. In this research, the products are nanorods of monoclinic LaPO4 and hexagonal CePOa structures and the vibration modes of PO4^3-, including the strong peaks at 227 nm for LaPO4, and at 225 and 278 nm for CePO4.Uniform lanthanide orthophosphate （LnPO4, Ln = La and Ce） nanorods were successfully synthesized by a simple ultrasonic irradiation method using lanthanide nitrate salt （Ln（NO3）3-6H2O, Ln = La and Ce） and sodium phosphate （Na3PO4） in aqueous solutions with the pH of 1-3.
