Measurement and simulation of exciton decay times in organic light-emitting devices with different layer structures

Intrinsic Radiative Decay Rate ${\Gamma }_r^0$ and Intrinsic Nonradiative Decay Rate ${\Gamma }_{nr}^0$ ^a

^a  Estimated from the linear fit in Fig. 2a for the three emitter materials. Intrinsic decay time ${\tau }^0$ , intrinsic luminescent efficiency ${\eta }_{\text{lum}}^0$ , and luminescent efficiencies ${\eta }_{\text{lum}}^{\text{LS}}$ for the three emitters in the six different LSs.
