TL;DR: In this article, a simple method for the preparation of surface-enhanced Raman-active gold films is reported, which involves sputter coating of gold to about 2000 A thickness on oxidized aluminium foils which yield surfaces of sub-micrometre roughness.
Abstract: A simple method for the preparation of surface-enhanced Raman-active gold films is reported. The method involves sputter coating of gold to about 2000 A thickness on oxidized aluminium foils which yield surfaces of sub-micrometre roughness. Self-assembled monolayers of thiols grown on these substrates yield good-quality Raman spectra. Monolayers with different functionalities have also been characterized by Raman scattering. © 1998 John Wiley & Sons, Ltd.
