| Abstract: Hollow ZnS spheres have been prepared in the presence of generation 3.5 poly (amidoamine) dendrimers with surface ester groups (G3.5-COOCH3 PAMAM dendrimer) as synthetic matrix template. The products obtained were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and UV-Vis absorption. TEM studies show that the hollow spheres with diameters ranging from 80 to 100 nm are prepared. The range of wall thickness was estimated to be about 20～30 nm. It was found that the concentration of PAMAM dendrimer had a significant influence on the formation of hollow ZnS spheres. The possible formation mechanism of the hollow spherical structure is also discussed. |
