Bismuth-doped tin dioxide (BTO) nanoparticles were prepared by a precursor approach with the aid of ultrasound radiation using SnCl4 and Bi(NO3)3 as the starting materials, with urea as a precipitation agent at a concentration of 9 M.The BTO nanoparticles were characterized by elemental analysis, powder X-ray diffraction (XRD), transmission electron microscopy (TEM), thermogravimetric analysis (TG), differential scanning calorimeter (DSC), atomic force microscopy (AFM) and ultraviolet-visual-near infrared diffuse reflection spectrum (UV-Vis-IR).The results show that BTO nanopaticles prepared by sonochemical method have excellent characteristics with a single-phase tetragonal structure, good dispersibility, good absorbency for ultraviolet ray and average particle size of 29.6 nm.
