Abstract

The relationship between the SERS signal intensity properties and the soaking times in a given concentration of 4-aminothiophenol (4-ATP) solution is experimentally investigated. The results show that the relationship depends on the specific position of the SERS excitation wavelength within the LSPR spectrum of the SERS substrates. In the case of LSPR peak wavelength of the SERS substrate located at the right side of ideal excitation wavelength arrangement, the SERS intensity no longer increases monotonically with the soaking time, which is different from the previous result reported.
