摘要/Abstract

摘要： 纳米多孔双金属不仅具有独特的三维纳米结构, 还可提供双金属协同光学特性, 成为表面增强拉曼散射 (surface-enhanced Raman scattering, SERS) 的良好候选材料. 以锆铜银非晶合金为前驱体, 采用脱合金工艺制备纳米多孔铜银双金属 SERS 基底. 具有均匀纳米孔隙的基底表现出优异的 SERS 性能, 对罗丹明 6G(rhodamine 6G, R6G) 和结晶紫 (crystal violet, CV) 的检测限分别达到10⁻¹⁶ 和10⁻¹⁰ mol/L. 同时, 所制备基底具有良好的均匀性和稳定性. 简单、高效、低成本纳米多孔铜银的制备为高性能 SERS 基底的实现提供了新思路.

Abstract: Nanoporous bimetals have unique three-dimensional nanostructures and synergistic optical properties, making them good candidates for surface-enhanced Raman scat-tering (SERS). A nanoporous copper-silver bimetallic SERS substrate was prepared by a dealloying process using a zirconium-copper-silver amorphous alloy as the precursor. The substrate with uniform nanopores showed excellent SERS properties. The detection limits for rhodamine 6G (R6G) and crystal violet (CV) were 10⁻¹⁶ and 10⁻¹⁰ mol/L, respectively. The substrate also exhibited good uniformity and stability. The preparation of simple, eﬃcient, and low-cost nanoporous copper-silver provides a new approach for the realization of high-performance SERS substrates.

Key words: surface-enhanced Raman scattering, nanoporous copper-silver bimetal, ultrasensitive detection
