| Résumé | Gold/silver (Au/Ag) bimetallic nanoclusters (shell) on silica (Au/Ag @ SiO 2) were synthesized by layer-by-layer technique. By adjusting the mole ratio of Au and Ag, the bimetallic alloy on the SiO 2 nanoshpere surface posseses tunable surface plasmon resonance. Several transmission electron microscopy (TEM) techniques have been applied to characterize the structure and morphology of the bimetallic nanoclusters, including scanning transmission electron microscopy (STEM) tomography, high angle angular dark field (HAADF) imaging, energy dispersive X-ray (EDX) spectoscopy, high resolution TEM (HRTEM) and electron diffraction (ED). The results revealed the Au/Ag alloy nanoclusters were interconnected on the surface of SiO 2 nanospheres with the nanoscale roughess varied with the mole ratio of Au and Ag. |
