Ag nanoparticle decorated MnO₂ flakes as flexible SERS substrates for rhodamine 6G detection.

ABSTRACT: Smart design of advanced substrates for surface-enhanced Raman scattering (SERS) activity is challenging but vital. Herein, we synthesized a new kind of AgNPs/MnO₂@Al flexible substrate as a SERS substrate for the detection of the analyte rhodamine 6G (R6G). The fabrication of porous MnO₂ nanoflakes on Al foil was conducted via a facile hydrothermal strategy. Owing to the large active surface area of the MnO₂ nanoflakes, the Ag nanoparticles were immobilized and displayed superior SERS performance with a low detection concentration of 1 × 10^-6 M for R6G. In addition, the SERS performance was found to be strongly related to the morphology of the MnO₂@Al substrate material. Our smart design may provide a new method of construction
