摘要：
Single-crystal BaWO4 nanoparticles have been successfully synthesized under microwave irradiation. The results show that nearly monodisperse BaWO4 nanoparticles have been successfully prepared without using surfactants. The products were characterized by X-ray powder diffraction (XRD), transmission electron microscopy (TEM), and photoluminescence (PL). The XRD results indicated that the BaWO4 nanoparticles obtained had a tetragonal unit cell (a = 0.5612, c = 1.2706 nm). The TEM images show that the as-prepared BaWO4 have good narrow particle-sized distributions containing a number of nanoparticles with uniform sizes. The products show a strong photoluminescence peak at 432-436 nm with the excitation at 365 nm. (C) 2011 Elsevier B.V. All rights reserved.
