The strength of a Raman signal is inversely proportional to the fourth power of the wavelength of the scattered light. In practical terms, this means that the longer the excitation wavelength used to ...
SERS offers a greater signal-to-noise ratio than ordinary Raman spectroscopy, so it is useful in single-molecule detection or detecting analytes in low concentrations. Improvement of the spectroscopic ...
