Silver coated gold nanocolloids entrapped in organized Langmuir-Blodgett Film of stearic acid: Potential evidence of a new SERS active substrate

- Au@AgNCs self assembled in the bilayer LB film of SA.
- The as prepared films have been established as a promising SERS active substrate.
- AEFs ∼1013 orders of magnitude have been estimated from the SER(R) S spectrum of R6G.
- Correlations between the optical properties and surface morphologies have been done.
- E-field distributions have been estimated with the aid of 3D-FDTD simulations.
