On the other hand, Fig. demonstrates the consequence of the disordered dark states cavity loss mechanism seen in Fig. for √ Ng c = 150 meV in an even more striking fashion. Not only are the largest long-time acceptor populations for λ D = 20 meV and λ D = 50 meV located at smaller values of Q, but the smallest long-time acceptor populations are seen at Q = ∞, even smaller than those at Q = 10. Further, the long-time acceptor population for λ D = 20 meV at Q = 50 is over 7 times larger than that at Q = ∞. While simulations with Q = ∞ may have a relatively fast rate of transfer to acceptor states at short times, much of the UP population quickly transfers to and becomes trapped in the dark states for λ D > 0 which forbids any appreciable transfer to the acceptor states during the rest of the 10 ns of propagation (we assume the dark exciton lifetime will be longer than this time scale, which is the case for CdSe NPL ). When λ D > 0 and Q is small, on the other hand, the recycling of population from the disordered dark states to the UP allows for the acceptor population to continue accumulating for the entire 10 ns of propagation even if the rate of accumulation at the start of the simulation is slower than for Q = ∞. This explains why the peaks in long-time acceptor population along Q in Fig. are more pronounced than the peaks in forward rate constant in Fig. .
