Abstract
- The three-dimensional (3D) MoS 2 decorated with Au nanoparticles (Au NPs) hybrids (3D MoS 2 -Au NPs) for surface-enhanced Raman scattering (SERS) sensing was demonstrated in this paper. SEM, Raman spectroscopy, TEM, SAED, EDX and XRD were performed to characterize 3D MoS 2 -Au NPs hybrids. Rhodamine 6G (R6G), fluorescein and gallic acid molecules were used as the probe for the SERS detection of the 3D MoS 2 -Au NPs hybrids. In addition, we modeled the enhancement of the electric field of MoS 2 -Au NPs hybrids using Finite-difference time-domain (FDTD) analysis, which can further give assistance to the mechanism understanding of the SERS activity.
