摘要
Au@Ag core-shell nanoparticles were prepared by seed-mediated growth method. The plasmon resonance properties of the core-shell nanoparticles are highly dependent on the size and shape of the core and thickness of the shell, which could be simply adjusted by varying the concentration of HAuCl4 and the volume of AgNO3. The prepared core-shell nanoparticles exhibit excellent SERS performance as substrate to detect rhodamine 6G (R6G). In addition, the precise control of core-shell morphologies (core size and shape, the thickness of the shell) is of significant importance as it strongly determines the overall SERS performance in micro chemical detection.
