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 ...
Fig. 1 THz wave generation from MoS2 through quantum interference. (a) Schematic diagram of THz wave generation from MoS2 under two-color light excitation at normal incidence. (b) THz waveforms ...
Yet, that does not get to the core of the actual difference between these two methods, and why SERS (surface-enhanced Raman scattering, or alternatively surface-enhanced Raman spectroscopy) is often ...
