A Facile Seed-Mediated Route to Au Nanoplates for SERS Application

Abstract

We have successfully synthesized Au nanoplates using a seed-mediated approach. Without the size-selection process, the yield of nanoplates in the as-obtained product was as high as 80 %. The nanoplate samples were characterized with TEM, SAED, XRD, UV-VIS-NIR and SERS spectroscopy. The results of SERS analyses demonstrate the potential of the anisotropicaily-shaped Au nanoplates as an active platform for Raman-sensitive analyte molecules.
