Abstract
Silver nanoplates were prepared by modified galvanic displacement on commercial copper foil. SEM, TEM, UV-vis and XPS were employed to analyze those closely packed silver nanoplates. This type of surface-enhanced Raman spectroscopy substrates showed strong surface plasmon absorption and reliable surface-enhanced Raman activity.
摘要
采用改良的置换反应在商用铜箔上制备了银纳米板。通过 SEM、TEM、UV-vis 和 XPS 对那些紧密堆积的银纳米板进行了分析。这种类型的表面增强拉曼光谱衬底表现出强的表面等离子体吸收和可靠的表面增强拉曼活性。
