Controlled synthesis of PbWO4 dendrites by a simple sonochemical method

In this paper, we report a simple sonochemical method to synthesize PbWO4 dendrites without any templates. The obtained products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The effect of the pH value, precursor and reaction time on the formation of PbWO4 dendrites was investigated. It is found that the obtained PbWO4 dendrites were composed of clusters of nanorods. It is rational to expect that dendritic structures of other oxides may also be synthesized by this simple method.
