| 摘要: 利用简易无模板湿化学法合成了由纳米片组装的具有三维分级结构的银纳米材料。场发射扫描电子显微镜表明柠檬酸氢二铵在这种结构形成过程中起到很重要的作用。X射线衍射和透射电子显微镜表征进一步证明了这种结构的形成。此外本文还对这种分级结构进行了紫外和拉曼表征。这种新型的银纳米结构有望作为一种高灵敏度的表面拉曼增强基底。 |

| Abstract: Three-dimensional (3D) hierarchical silver nanomaterials (HSNs) were prepared by a simple surfactant-free wet-chemical method at room temperature. The as-prepared HSNs exhibit spherical morphologies and are constructed with many 2Dnanoflakes as building blocks. Field emission scanning electron microscopy (FESEM) studies show that diammonium 2-(carboxymethyl)-2-hydroxysuccinate (diammonium hydrogen citrate) (C6H14N2O7) plays a key role in the formation of such HSNs. X-ray diffraction (XRD) and transmission electron microscopy (TEM) results confirm the formation of HSNs. The optical properties and surface-enhanced Raman scattering (SERS) effect were also investigated by UV-Vis and Raman spectra. The HSNs could be served as highly sensitive surface-enhanced Raman scattering (SERS) substrates for chemical detection. |
