Abstract:
Here, 3D hybrid plasmonic nanostructures using monolayer MoS 2 as sub‐nanometer spacer with high density hot spots are fabricated. For the 3D hybrid assemblies, the hot spots exist not only on the 0.65 nm thick MoS 2 gap regions between large and small nanoparticles (NP) but also between small and small NP. The high‐density hot spots induce prominently enhanced optical absorption, huge surface enhanced Raman scattering effect, excellent reproducibility, and ultralow limit of detection. Besides, the obvious electron transfer between MoS 2 and metal NP is also found in the 3D hybrid assemblies indicating the strong interactions between MoS 2 and Au or Ag. Combined with the long‐term stability, the 3D hybrid assemblies should perform excellent in plasmon‐enhanced sensor and photocatalysis applications.
