From: New insights into detecting alizarin from autofluorescence in marked glass eels
Excitation-Emission Matrix (EEM) fluorescence spectra. The EEM spectrum of (a) an alizarin red S solution (150 ppm) and as examples of EEM spectra obtained the EEM spectrum of (b) a marked glass eel and (c) a control glass eel. Fluorescence intensities are given in arbitrary units (a. u.).
