Figure 3.

Experimental (a) and theoretical (b) extinction spectra of the hybrid system of J-aggregates and core–shell Au@Ag nanorods for different aspect ratios; all spectra are normalized to their maxima, A_max. Experimental (c) and theoretical (d) MCD spectra, ΔA, normalized to the magnitude of the magnetic field B and to the corresponding extinction maxima, A_max. MCD spectra were measured under the applied magnetic fields of B = ±1T (solid and dashed lines for positive and negative, respectively). All spectra were obtained at room temperature.
