Cu L3- and L2-edge NEXAFS spectra for Cu2O (representative example of highly concentrated absorbing element), before (left panel) and after (right panel) the background subtraction and normalization provided by the splines method. The yellow and red vertical lines and the colour-related points indicate the selected pre-edge and post-edge regions, respectively. The green dashed line denotes in both graphs the position of the energy position of the absorption edge (E0). |
