Figure Lengend Snippet: Au@Ag NSs/PPSi composite substrate FDTD simulation model and electromagnetic field distribution. (a) Au@Ag NSs/Si simulation model and electromagnetic field distribution. The intensity of the electromagnetic field | E / E 0 | 4 was represented by color scale. (b) Au@Ag NSs/PPSi SERS substrate FDTD simulation model. (c) Electromagnetic field distribution of composite SERS substrate with a height of 8.4 μm.
Article Snippet: To better understand the enhancement mechanism and behavior of the Au@Ag NSs/PPSi composite SERS substrate, finite difference time domain (FDTD) simulation was conducted using Ansys Lumerical software to calculate the local enhanced electric fields of Au@Ag NSs/Si and Au@Ag NSs/PPSi.
