Synthesis of core-shell nanocubes for higher SERS enhancement
Abstract
Palladium nanocubes and gold nano-octahedral core and palladium shell nanocubes are synthesized by seed mediated chemical synthesis. Both the Pd nanocubes and Au@Pd nanocubes are characterized by an analytical Transmission Electron Microscopy and the composition of core-shell nanocubes were analyzed by Energy Dispersive X-ray spectroscopy (EDX). The near field electric field distribution around the nanocubes are simulated by FDTD simulation which shows higher electric field around the core shell nanocubes compared to monometallic counterpart due to the insertion of Au core which also results in higher SERS enhancement.
