Surface-enhanced Raman spectra, scanning electron microscopy image, and Raman micromapping. Surface-enhanced Raman spectrum (red curve) of the hybrid nanostructure of gold nanostars and the J-aggregates of JC1 dye as compared to the Raman spectrum of J-aggregates of JC1 only (black curve). Scanning electron microscopy image and Raman micromapping of tightly bound agglomerates of gold nanostars and J-aggregates of JC1 dye are given in the left and the right insets, respectively.
