Bimetallic (Ag)Au nanoparticles prepared by the seed growth method: Two-Dimensional assembling, characterization by energy dispersive X-ray analysis, X-ray photoelectron spectroscopy and surface enhanced Raman spectroscopy, and proposed mechanism ...

Abstract

Preparation, two-dimensional assembling, characterization by EDAX, XPS and SERS of bimetallic (Ag)Au nanoparticles are reported. The results are consistent with Ag core and Ag/Au alloyed shell composition of the nanoparticles.
