Cooperative luminescence quenching on many-particle acceptors in disordered media

► Complex form of static quenching kinetics is due to averaging over different acceptor surroundings. ► Down-conversion-cooperative quenching of one donor to n-particle acceptors is still more complex. ► We present Förser-like law for long stage of cooperative quenching in a diluted crystal or glass. ► We Monte-Carlo simulated cooperative quenching confirming validity of our derivations.
