Fanxin Liu, Xuhong Ye, Chaojun Tang and Hongtao Ma Silver macro-texture substrates fabricated by plasma selective etching for surface-enhanced Raman scattering Journal of Raman Spectroscopy 44
We demonstrated a novel method of plasma selective etching combining with deposition of a silver film to generate a SERS substrate. This substrate shows a spatially uniform enhancement factor of approximately 106. Finally, we combine this novel Ag marco-texture substrate with a 10 Å ta -C film and get a higher enhancement than the uncoated Ag marco-texture substrate.
