▎ 摘　　要

Graphene oxide (GO) patterns on glass slides are prepared by microcontact printing, on which silver firms are produced in situ through a straightforward one-step chemical method in aqueous silver nitrate solution at 60 degrees C, Using encase as. a reductant. The obtained silver films are uniform and well-shaped, which are investigated by optical microscopy, scanning electron microscopy, atomic force microscopy, X-ray photoelectron spectroscopy, and Raman spectroscopy. The surface-enhanced. Raman scattering phenomena of the GO pattern resulting from the silver film give more hyperfine structural characteristics. Using the silver film as a reducing pattern, gold nanoparticles on GO patterns are obtained by simply immersing the silver pattern in a HAuCl4 solution. Our method is a convenient and ecofriendly approach to produce well-shaped silver. Or other metal nanoparticle patterns on different substrates.
