Green synthesis and electrophoretic deposition of Ag nanoparticles on SiO2/Si(100). Giallongo, G., Rizzi, G. A., Weber, V., Ennas, G., Signorini, R., & Granozzi, G. Nanotechnology, 24(34):345501, August, 2013.
Paper doi abstract bibtex Plasmonic substrates were prepared by electrophoretic deposition of Ag nanoparticles on SiO2/Si(100). The Ag nanoparticles were obtained using [Ag(NH3)2]+ as the Ag precursor and d-glucose as the reducing agent. Under optimized conditions, this simple and green synthesis method furnished a suspension of Ag nanoparticles with a narrow dimensional dispersion (centered around 27 nm) and a negative z-potential, suitable for electrophoretic deposition. Samples were chemically, optically and morphologically characterized by photoemission and UV–vis spectroscopy and electron microscopy, and tested as substrates for surface enhanced Raman spectroscopy. Despite being a very simple procedure, good enhancement factors were measured thanks to the formation of hot spots, formed by sandwiching the analyte (benzenethiol) between sequentially deposited Ag nanoparticles.
