| Abstract: | Ethylene glycol was used as the solvent and reductant for preparation of silver nanoparticles with the method of hydrothermal reduction. The structure of the particles was characterized by X-ray diffraction(XRD), transmission electron microscopy(TEM) and UV-Vis adsorption spectrum. The results indicated that the silver nanoparticles have fcc polycrystalline structure and the mean diameter is about 30nm. The absorption peak is about 380nm. The influences of dispersant and water content on the size of silver particles were also studied. |
