Abstract

Surface enhanced Raman scattering (SERS) signal fluctuate due to position between near field and adsorbed molecules. According to past works, the frequency of the bright period follows a power law. The purpose of this study is to analyze the blinking behavior of SERS spectra by Density-Based Spatial Clustering Analysis with Noise (DBSCAN) with temporal resolution higher than a conventional spectroscopic method. As a result, it was confirmed that the SERS blinking actually follows the power law even under adverse conditions such as extremely low sample concentration and a very short exposure time of 10 ms.
