Abstract
Recently, we reported the accurate rate equation set to analyze the kinetics of three-state photophysics for the thermally activated delayed fluorescence (TADF) materials. The accurate rate constant could be estimated with the simple equation approximated to be no phosphorescence in emission, and the non-radiative decay rate was resulted to be 0. Therefore, the rate constants should be provided as the possible ranges when it is necessary to consider the non-radiative decay from triplet etc. In here, we introduce how analyze the actual emission decays profile which be fit with not only the bi- but also tri-exponential curves to analyze TADF.
