Quasi‐Periodical 3D Hierarchical Silver Nanosheets with Sub‐10 nm Nanogap Applied as an Effective and Applicable SERS Substrate

A new hierarchical structure of silver nanosheets is fabricated using chemical deposition methods. This silver film with 3D nanogaps acts as an efficient and sensitive surface enhanced Raman scattering (SERS) substrate, with abundant hot spots.
