(a) SERRS measurements of the aligned FF-PNT/Ag NP template with TMPyP following UV irradiation. (b) SERRS measurements recorded following 45 minutes of UV irradiation, showing the relaxation of the signal. (c) Plots of intensity vs. time following 5 minute irradiation steps (blue), after turning the UV lamp off after 45 minutes of total UV irradiation (orange), and in the absence of UV irradiation (red). (d) A comparison of normalized SERRS spectra with (red) and without (purple) UV irradiation.
