Synthesis of gold-tin alloy nanoparticles with tunable plasmonic properties.

ABSTRACT: Plasmonic nanoparticles and nanocrystalline materials have broad applicability in catalysis, optoelectronics, sensing, and sustainability. Below, we detail a robust protocol for the synthesis of bimetallic Au-Sn nanoparticles in mild, aqueous conditions. This protocol describes the steps for synthesizing gold nanoparticle seeds, diffusing Sn into the seeds by chemical reduction, and the optical and structural analysis by UV-visible spectroscopy, X-ray diffraction, and electron microscopy. For complete details on the use and execution of this protocol, please refer to Fonseca Guzman et al.¹.
