The Kinetics of Joined Action of Triplet-Triplet Annihilation and First-Order Decay of Molecules in the State in the Case of Nondominant First-Order Process
Figure 2
The fitted parameters as dependent on the delay (the starting point of evaluation—) obtained for the delay of anthracene in cis/trans-DMCH at 146 K for middle excitation pulse. Part (a): first-order rate constant : squares ()—delayed fluorescence, exponential fit (21); circles ()—delayed fluorescence, nonexponential fit (17); solid line ()—phosphorescence, exponential fit; dashed lines—accuracy of ; dash-dotted line ()—phosphorescence, nonexponential fit; dash-dot-dotted lines—the accuracy of (). Part (b): main plot indicator of nonexponential () behavior; right inset: comparison of smoluchowski parameter () for nonexponential fit (lower curve) and exponential fit (upper curve); left inset: autocorrelation function for nonexponential fit (lower curve) and exponential fit (upper curve).
