Abstract:Metal/semiconductor hybrids are ideal substrates for efficient surfaceenhanced Raman scattering (SERS) due to the cooperation of electromagnetic field and charge transfer, while it remains a challenge to simultaneously optimize the two enhanced mechanisms to achieve higher SERS improvement. Herein, a boat-like Au/ PbS/Au hybrid is synthesized for the first time, which shows improved SERS activity caused by the synergetic effect of huge electromagnetic enhancement and electromagnetic-field-accelerated charge tr… Show more
