Fig. 7From: Formation Regularities of Plasmonic Silver Nanostructures on Porous Silicon for Effective Surface-Enhanced Raman ScatteringDependence of SERS-signal intensity on the time of PS immersion in 1, 3 and 10 mM AgNO3 solutions. A 10−6 M CuTMpyP4 aqueous solution was used as analyte solution. The SERS-signal intensity of the 1366 cm−1 band in the SERS spectrum of 10−6 M CuTMpyP4 was estimatedBack to article page
