文摘

Densely arranged nanocavity array have been constructed on the silver-based SERS substrate. The SERS substrate demonstrated remarkable SERS sensitivity and high homogeneity for SERS signal distribution across the substrate surface. High SERS sensitivity for R6G and PCB77 molecules have been achieved. Cone-shaped nanocavity benefits the captivity of PCBs molecules.
