Representation of the spectra and energy diagrams for three different scenarios in which an excited state loses its energy; in the absence and in the presence of a PhBG (the PhBG position is superposed on the spectrum in a dotted line). (a) A single molecule. (b) A FRET donor-acceptor pair. (c) BAlq (dash line) and Ir(ppy)3 (solid line). The squared areas denote the overlapping of bands. The thickness of the arrows can be interpreted, qualitatively, as intensity. The values are not to scale.
