| Abstract: | Preparation of silver nanoparticles by thermal decomposition of precursors.Three phases,liquid(a mixture of oleic acid and ethanol),and solution(a water-ethanol solution containing Ag ions),and sodium oleate spontaneously form in this system.Ethanol in the liquid and solution phases reduces Ag ions at the liquid-solid or solution-solid interfaces.The size of silver nanoparticles is about 25nm.The as-prepared nanomaterials are characterized by XRD,TEM,SEM and their growth mechanism is also briefly investigat... |
