Abstract

Many ways to produce plasmonically-active substrates used for SERS applications, which is a non-destructive and reliable spectroscopy method, have been tried in recent years. Here we have presented an economical and easy procedure for synthesizing Ag NSs on Cu-grid in one step. Structural and elemental characterizations of Ag NSs on the Cu-grid were performed by scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), X-ray diffraction (XRD), and X-ray photoelectron spectroscopy (XPS). Ag NSs on Cu-grids cause a high electromagnetic increase due to having complex morphology. Thus, the determination of R6G is easily realized even at very low concentrations such as 100 pM. It is predicted that different metallic nanostructures can be obtained by applying a similar recipe for different applications.
