The Regulation of Surface-Enhanced Raman Scattering Sensitivity of Silver Nanorods by Silicon Sections
Figure 3
Raman spectra of R6G (concentration of 10−6 M), characterized by aligned nanorods, consisted of four silver sections with 25 nm length and five silicon sections with length of 20 nm, 30 nm and 60 nm, respectively; the Raman spectra are substracted by baseline and added by constant line to make the three Raman spectra separated.
