(a) The SERS spectra of 1-DDT-covered Ag nanocubes in water at four different solution temperatures with 514 nm excitation. The temperature of the solution was adjusted with a temperature-controlled stage. Each spectrum contains the gauche (G, at 1080 cm−1) and trans (T, at 1125 cm−1) carbon-carbon stretch of the 1-DDT SAMs with the scale bar corresponding to 10.8 adu mW−1 s−1. (b) The relationship between temperature and peak intensities of the T and G bands, where an increase in the solution temperature causes the T band to attenuate and the G band to increase.
