| According to the previous studies, the fast components around 0.2~0.8 ns are ascribed to the lifetime of intrachain excitons of PCFOz, i.e., the single chain or other isolated chromophore in Polyfluorene derivatives, and the long components around 2 ns are ascribed to the lifetime of interchain excitons (Monkman, A., et al., Advances in Polymer Science, 2008. 212: 187-225); a relatively long lived third one (5.5~7.4 ns) with small lifetime weighted fractional intensity (A% < 5) is assignable to charge-transfer (CT) emission. |
