| Summary: | © 2014, The Nonferrous Metals Society of China and Springer-Verlag Berlin Heidelberg. Uniform lanthanide orthophosphate (LnPO<inf>4</inf>, Ln = La and Ce) nanorods were successfully synthesized by a simple ultrasonic irradiation method using lanthanide nitrate salt (Ln(NO<inf>3</inf>)<inf>3</inf>·6H<inf>2</inf>O, Ln = La and Ce) and sodium phosphate (Na<inf>3</inf>PO<inf>4</inf>) 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 LaPO<inf>4</inf> and hexagonal CePO<inf>4</inf> structures and the vibration modes of PO<inf>4</inf> <sup>3−</sup>, including the strong peaks at 227 nm for LaPO<inf>4</inf>, and at 225 and 278 nm for CePO<inf>4</inf>. |
