Nanostructured silver films have been prepared by thermal deposition on silicon, and their properties as SERS substrates investigated. The optimal conditions of the post-growth annealing of the substrates were established. Atomic force microscopy study revealed that the silver films with relatively dense and homogeneous arrays of 60-80-nm high pyramidal nanoislands are the most efficient for SERS of both organic dye and inorganic nanoparticles analytes. The noticeable enhancement of the Raman signal from colloidal nanoparticles with the help of silver island films is reported for the first time.
通过热沉积在硅上制备了纳米结构银膜，并研究了它们作为表面增强拉曼散射（SERS）基底的性能。确定了基底生长后退火的最佳条件。原子力显微镜研究表明，具有相对致密且均匀排列的60 - 80纳米高金字塔形纳米岛的银膜对于有机染料和无机纳米颗粒分析物的SERS最为有效。首次报道了借助银岛膜显著增强胶体纳米颗粒的拉曼信号。
