Non-linear effects in the quenching of fluorescent quantum dots by nitroxyl free radicals.

Abstract

Quenching of quantum dot luminescence by nitroxides is extremely non-linear and dependent on nanoparticle size, being most effective for the smaller particles; it is proposed to involve an electron exchange mechanism.
