Electrodeposition of hierarchical Ag nanostructures on ITO glass for reproducible and sensitive SERS application

Abstract In this paper, electrodeposition of relatively uniform hierarchical Ag nanostructures (the RSD of size is about 28.8%) on ITO glass has been achieved via utilizing low precursor concentration and complexing agent without any surfactant. The RSD of SERS intensity (rhodamine 6G, R6G) for 1651 cm−1 band is about 14.9% and the detectable concentration of R6G can be 10−10 M at least, indicating the hierarchical Ag nanostructures on ITO glass good candidate for reproducible and sensitive SERS application.
