Abstract：
Nano-sized semiconductors ZnO were synthesized with an upgraded reverse micelles by using DDAB (Didodecyldimethyl-ammounium bromide) as capped surfactants. The main advantage of this procedure is that the water needed to form micro reactors comes directly from intra molecule of Zn salt. The radius of nano-sized ZnO can be controlled by changing the concentration ratio of Zn salt and DDAB in organic solvent, and monitored by TEM images. XAFS spectroscopy is then used to recognize the distortion and the recombination on the surface of nanomaterial.
