\(\beta\) versus current density, as a function of \({k}_{{TP}}\) values for mCP:4CzIPN OLEDs. In the plot, dominating loss mechanism to singlet density via STA (negative regions) or indirectly TPA (positive regions). The line ‘0’ represents the contour where the loss due to STA and TPA individually results in the same singlet density. The dash-dot straight line represents experimentally obtained \({k}_{{TP}}\) as 9.1 × 10−13 cm3 s−1 for 4CzIPN.
