| 摘 要： | 采用柠檬酸三钠作为保护剂，通过水合肼还原的方法合成了不同组成的Au-Ag合金纳米粒子。UV-Vis光谱中只观察到一个位于单金属银和金之间的等离子体共振峰, 表明金银已形成合金。TEM显示合成的粒子非核壳结构，金银分布均匀, 合金粒径在25 nm左右。用吡啶为探针分子研究了合金的表面增强拉曼光谱(SERS), 结果表明吡啶在合金表面表现出了不同于纯金和纯银的行为。

| Abstract: | Using citrate as protector,Au-Ag alloy nanoparticles with different molar ratios were prepared by using hydrazine as the reducer,One plasmon band between that of monometallic Ag and Au observed in their UV-Vis spectra indicated the formation of Au-Ag alloy nanoparticles.TEM results showed diameters about 25 nm and homogeneous color of the alloy nanoparticles without clear core-shell contrast.By using Pyridine as the probe molecules,SERS studies were performed.The results indicated the spectra of Pyridine adsorbed on alloy is different from that of Ag and Au. |
