Figure 5From: Morphology and composition controlled synthesis of flower-like silver nanostructuresSERS spectra and Raman Spectra of R6G and 4-ATP. SERS spectra of 10−7 M R6G (A) and 4-ATP (B) using flower-like Ag nanostructures as SERS substrates, and Raman spectra 10−2 M R6G and 4-ATP on bare silicon wafer are also presented for comparison.Back to article page
