Assembly Nanoparticle Arrays Decorated with Ultrathin AAO Nanopores for Highly Sensitive SERS Substrate
Surface-enhanced Raman scattering (SERS) is widely employed because it offers quick, microscopic, and traceless detection. This study used high-voltage and low-voltage ultrasonic oscillation to embed gold-silver nanoparticles (Au-Ag NPs) into the pores of chemically modified ultrathin anodic alumina (AAO) films, resulting in a highly sensitive three-dimensional SERS substrate. We improved the substrate’s stability and Raman activity by adjusting the particle alloy ratio. For the substrate in this alloy ratio, the Raman signal of probe molecules (Rh6G) adsorbed on the substrate surface is enhanced. the enhancement factor (EF) was as high as 1.40 × 107, the relative standard deviation (RSD) of 10.6%, and the concentration of Rh6G shows a linear relationship with Raman intensity, with a linear correlation coefficient of 0.961. In addition, we evaluated the substrate’s detection effect on thiram molecules. It has been proven that this structure has good practicality and high sensitivity as a Raman enhanced substrate.
期刊介绍：
Plasmonics is an international forum for the publication of peer-reviewed leading-edge original articles that both advance and report our knowledge base and practice of the interactions of free-metal electrons, Plasmons.
Topics covered include notable advances in the theory, Physics, and applications of surface plasmons in metals, to the rapidly emerging areas of nanotechnology, biophotonics, sensing, biochemistry and medicine. Topics, including the theory, synthesis and optical properties of noble metal nanostructures, patterned surfaces or materials, continuous or grated surfaces, devices, or wires for their multifarious applications are particularly welcome. Typical applications might include but are not limited to, surface enhanced spectroscopic properties, such as Raman scattering or fluorescence, as well developments in techniques such as surface plasmon resonance and near-field scanning optical microscopy.
