Red edge wavelength
WebIndices with red-edge wavelengths The 'red edge' is the name given to the abrupt reflectance change in the 680 ± 740 nm region of vegetation spectra that is caused by the combined … Weblonger wavelengths located at the red edge of the exci-tation spectrum [12]. Excitation at a lower energy selects for fluorophores in a solvent-relaxed environ-ment, which require less energy to become activated. Experimentally, one observes a red shift in the emis-sion maximum with respect to excitation wavelength.
