摘要

In this work, we report a new strategy to prepare silver (Ag) nanoparticles (NPs) from bulk Ag substrates. First, positively charged Ag ions were prepared by electrochemical methods in 0.1 N HNO3 aqueous solutions. Then the solutions were heated from room temperature to 100 °C at a heating rate of 6 °C/min to prepare Ag nanoparticles. The average particle size of the prepared Ag NPs with predominant (111) face is ca. 10 nm. Experimental results indicate that the prepared Ag (111) nanoparticles in solutions are surface-enhanced Raman scattering (SERS)-active, which are examined by probe molecules of Rhodamine 6G.
