Full Spectrum Raman Excitation Mapping Spectroscopy [PDF]

Scientific Reports, 2020
AbstractA generalization of the Raman scattering (RS) spectrum, the Raman excitation map (REM) is a hyperspectral two-dimensional (2D) data set encoding vibrational spectra, electronic spectra and their coupling. Despite the great potential of REM for optical sensing and characterization with remarkable sensitivity and selectivity, the difficulty of ...
