Hierarchically rough CuO/Ag composite film with controlled morphology as recyclable SERS-active substrate

Qiong Yang et al.

Summary: In this study, a hierarchically rough CuO/Ag composite film with good SERS performance and recyclability was prepared by loading silver nanoparticles onto a copper oxide film with hierarchical micro/nanostructures. The CuO/Ag composite substrate can degrade surface adsorbed molecules under light irradiation, achieving self-cleaning and reusable. With the optimized composite film as the SERS active substrate, low detection limits for R6G and CV molecules were achieved. The hierarchical CuO/Ag composite film has great potential for efficient SERS sensors.
