We report on the formation of silver subsurface ion-exchanged metal oxide (silver SIMO) glasses and their surface-enhanced Raman scattering (SERS) activity. The samples were prepared by a combined thermal and chemical three-step methodology and characterized by transmission electron microscopy (TEM), atomic force microscopy (AFM), environmental electron scanning microscopy (ESEM), and UV/Vis spectroscopy. This unique method provides SERS substrates with protection against contamination and strong, reliable and reproducible SERS enhancement. The Raman enhancement factors of the long-term stable SIMO glasses were estimated to approximately 10(7).
我们报告了银亚表层离子交换金属氧化物（银 SIMO）玻璃的形成及其表面增强拉曼散射（SERS）活性。这些样品是通过热化学三步法结合制备的，并通过透射电子显微镜（TEM）、原子力显微镜（AFM）、环境电子扫描显微镜（ESEM）和紫外/可见光谱进行了表征。这种独特的方法为 SERS 基底提供了免受污染的保护，并具有强大、可靠和可重复的 SERS 增强效果。长期稳定的 SIMO 玻璃的拉曼增强因子估计约为 10(7)。
