摘要：

We present here a theoretical analysis of the possibility to combine SERS with THz by investigating the electromagnetic enhancement effect of gold nanoparticles with visible to near-infrared and THz excitation. By means of the FDTD simulations, the electrical field enhancement, and thus the SERS enhancement factor of the gold nanoparticles with different sizes and interparticle separations are demonstrated, which indicate that the SERS effect exists in THz range as well and the SERS enhancement factor could reach 10(5) for 10 THz under the condition of certain size and interparticle distance. Therefore the SERS effect could be extended from ultraviolet, visible and near-infrared to THz regime.
