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.
