Here, we report a simple strategy to prepare highly sensitive surface-enhanced Raman spectroscopy (SERS) substrates based on Ag decorated Cu2O nanoparticles by combining two common techniques, viz, thermal oxidation growth of Cu2O nanoparticles and magnetron sputtering fabrication of a Ag nanoparticle film. Methylene blue is used as the Raman analyte for the SERS study, and the substrates fabricated under optimized conditions have very good sensitivity (analytical enhancement factor similar to 10(8)), stability, and reproducibility. A linear dependence of the SERS intensities with the concentration was obtained with an R-2 value >0.9. These excellent properties indicate that the substrate has great potential in the detection of biological and chemical substances.
