Collaborative work between groups in Singapore, Hong Kong and Prof. Lucio Isa, Interfaces, Soft matter and Assembly, in D-MATL has lead to the fabrication of novel plasmonic devices.
The researchers found that tunable superlattices of silver octahedra can be fabricated via self-assembly at a liquid/liquid interface after controlled surface chemistry modifications of the particles. Contrary to previous belief, they demonstrate that open superlattices of standing octahedra lead to nearly ten-fold higher efficiency for surface-enhanced Raman scattering compared to more closely packed structures.
