Effects of Surfactants on the CoSb_3 Nanopodwers and Amorphization of the Synthesized Nanopodwers

The CoSb_3 nanopodwers were synthesized by the hydrothermal method using different surfactants which were Cetyltrimethyl Ammonium Bromide(CTAB),Ethylene Diamine Tetraacetic Acid(EDTA),sodium dodecyl benzene sulfonate(SDBS) and Polyvinyl Pyrrolidone(PVP). The phase structure and micro-topography of the nanopowders were investigated by X-ray diffractometer(XRD) and a fileld-emission scanning electron microscopy(FESEM).The result showed that different surfactants had significant influence on the morphologies of CoSb_3 nanopodwers. Laser rapid quenching method was used to deal with CoSb_3 nanopowders that synthesized by the hydrothermal method in order to achieve partial amorphization of the CoSb_3.The amorphous conditions of CoSb_3 were investigated by the XRD. The results showed that(1) with the increase of the scanning number,the amorphous level of CoSb_3 raised;(2) Increasing the scanning speed properly could be helpful to increase the amorphous level of CoSb_3.
