Synthesis and photoluminescence of Pb5(VO4)3OH nanocrystals

Pb5(VO4)3OH nanocrystals with different morphologies and sizes were prepared through chemical precipitation processes in the presence of different surfactants-dodecyl dimethylbenzylammonium bromide (DDBAB) or sodium dodecylbenzenesulfonate (SDBS), respectively. The products were characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The role of surfactants in the synthesis process had been tentatively proposed. Luminescence of the Pb5(VO4)3OH nanocrystals were also investigated by photoluminescence spectroscopy.
