| Abstract: | Plasmonic black gold film from Au NPs was prepared via salt-induced self-assembly and sedimentation method. That were accomplished by addition of inorganic salt into Au colloids to induce the self-assembly of Au NPs and subsequent sedimentation of the resultant Au NP assembly into black Au film. The as-prepared black Au film shows strong absorption capability(>80%) in a broadband range of 400-1600 nm, reaching 94% in the visible range of 400-800 nm. Consequently, it shows high light-heat conversion capability and broadband high surface-enhanced Raman scattering(SERS) activity. These results, thus, offer a facile preparation strategy for plasmon black Au, which shows great potential in seawater desalination, quick SERS detection, and beyond. |
