| 中文摘要: |
| 通过置换反应在金属铜表面制备了表面没有任何保护剂且具有红外增强作用的松针枝状银，并应用扫描电子显微镜、X射线衍射和红外光谱对其形貌和性质进行表征。结果表明:虽然松针状银的松枝和松针长度都在微米级，但松针的直径却是纳米级的；首次发现具有这种特殊结构的银对吸附于其表面的有机分子的红外吸收光谱有较大的增强作用，使得表面增强红外光谱可以用于痕量分析、检测。 |
| 英文摘要: |
| Pine needles dendritic silver, which without protective agent but has infrared enhancement effect, was prepared on the metal copper surface by replacement reaction. And the morphology and characteristics were investigated by using SEM, XRD and IR. The results showed that the length of pine branches and pine needles of silver were micron while the diameter of pine needles was nanoscale. Herein, we introduce a new finding, revealing that silver’s unique structure enables a significant enhancement effect on infrared absorption spectrum of organic molecules which are adsorbed on the surface of silver particles. So the surface-enhanced infrared spectroscopy can be used for trace analysis and testing. |
