Abstract:
Analytic expression is given for the static cooperative quenching kinetics in crystals with arbitrary acceptor concentration and arbitrary multipolarity of interaction. For the quenching by two acceptors, the results of Monte-Carlo simulation are also presented which can be approximated in the long-time domain by the nonexponential law $I(t)\cong\exp{[-(wt)^k]}$, with $k=0.41, 0.3$, and $0.25$ for the multipolarities $S=6, 8$, and $10$, respectively.
