Fig. 9From: Formation Regularities of Plasmonic Silver Nanostructures on Porous Silicon for Effective Surface-Enhanced Raman ScatteringSERS spectra and detection limit of the CuTMpyP4 molecules adsorbed on the Ag/PS substrates. 10−6–10−11 M CuTMpyP4 aqueous solutions were used as analyte solutions. The Ag/PS substrates were formed by the immersion deposition of silver on PS from 3 mM AgNO3 solution for 40 minBack to article page
