Figure 2 Caption - PL properties. (a) UV-vis absorption spectra (dashed lines) and PL spectra (solid lines) in dilute toluene; (b) fluorescence (FLUO.) and phosphorescence (PHOS.) spectra of the investigated materials in 50 wt%-doped PPF films; (c) transient PF and DF decay curves of the investigated materials in 50 wt%-doped PPF films; (d) UV-visible absorption spectra of v-DABNA in dilute toluene (dashed lines) and PL spectra of the investigated materials in 50 wt%-doped PPF films (solid lines); (e) PL spectra of v-DABNA and TSF systems; (f) transient PF and DF decay curves of the TSF systems.
