%X CdS hollow nanospheres were synthesized via solvothermal route from cadmium nitrate and thiourea with methanol as medium. Morphology and structures of the as-obtained products were characterized by TEM, EDS and XRD. TEM and EDS analysis show that the products are mainly onion-like CdS hollow nanospheres, with external diameter of 5￡17nm and hollow inner size of 3￡14nm. XRD tests indicate that these hollow nanospheres exhibit hexagonal wurtzite structure. The function of alcohol solvent on the growth of CdS nanostructure is also studied preliminary. As absolute ethanol or 1-pentanol is employed as a substitute for solvent, the products are congeries of CdS nanoparticles and microspheres assembled by CdS nanoparticles, respectively. The results demonstrate that methanol plays a significant role in the formation of hollow structure. The formation of hollow nanospheres may be caused by curling of CdS nanoflakes under the high vapor pressure of methanol.a¤
