Abstract

Abstract: A gold-silver nanoframe monolayer nanostructure was obtained on the glass slide using the in-situ sacrificial template reaction. First the silver nanoprisms(~79.2 nm edge length) were prepared as the sacrificial template and were assembled on the slides through electrostatic interactions. The chloroautric acid in-situ reacted with the silver nanoprisms as oxidant. We evaluated the effect of oxidation reaction time on the morphologies and the LSPR properties of the prepared nanoframes. The thickness of gold-silver framework can be adjusted from 29.3 nm to 16.2 nm. We applied the gold-silver framework monolayer as a new surface-enhanced Raman scattering(SERS) substrate for determining 4-aminothiophenol.

Key words: Gold-silver framework monolayer nanostructure, Sacrificial template, Surface-enhanced Raman scattering
