Fig. 5From: In vivo label-free mapping of the effect of a photosystem II inhibiting herbicide in plants using chlorophyll fluorescence lifetimeFluorescence emission spectra of chlorophyll and Flagon EC 400, when excited at 440 nm (curve normalized to maximum Flagon fluorescence). The transmission band of the emission filter used for wide-field FLIM is also plotted to show the spectral range of detection. The emission curves are scaled according to the data from control experiments carried out using the multispectral point-probe spectrofluorometerBack to article page
