Figure | Electric-field-modulated interlayer bond polarizability model for plasmon-enhanced LB modes in AuNCs/NLG.  (a)  FDTD-simulated distribution of normalized x-component of local field in different graphene layers near AuNCs. (b) Simulated x-component of local field at graphene layers near AuNCs and a schematic of AuNCs/NLG with interlayer bond polarizability derivatives. (c) Measured PERS spectra with λL=633 nm and (d) the calculated IM and LB modesof AuNCs/NLG (N=5, 10, 15, 20) by E-IBPM. (e) SEM images and the (f) corresponding Raman spectra of as-prepared AuNCs/8LG, AuNCs/8LG annealed at 600 °C, as-prepared AgNCs/8LG and AgNCs/8LG annealed at 400 °C. Scale bars in (e): 250 nm.
