Abstract
Surface enhanced Raman spectroscopy (SERS) is a highly sensitive chemically specific method that is capable of trace analyte detection.
1–3
One challenge with SERS is that the spectrum must be stable and consistent to accurately identify compounds. The localized surface plasmon resonance (LSPR) that enhances the Raman signal can cause chemical transformations on molecules near the nanoparticles. The SERS peaks can fluctuate in intensity and position, indicating the presence of transient species like ions or other products from photo-induced reactions. The background of SERS spectra has also been observed to increase or decrease depending on the experiment.
4–9
All of these effects are convoluted with the role of heating that also results from excitation of the LSPR. This thesis attempts to identify spectral fluctuations due to heating as well as to shed some light on the inner workings of the background observed in the spectra.
