Here we address the effect of surplus charges on non-radiative (NR) exciton and trion decay in doped semiconducting single-wall carbon nanotubes. The dependence of exciton photoluminescence quantum yields and exciton decay on the doping level, with its characteristically stretched-exponential kinetics, is attributed to diffusion-limited NR decay at charged impurity sites. By contrast, trion decay is unimolecular with a rate constant of $2.0\\,\\rm ps^{-1}$. Our experiments thus show that charged impurities not ","authors_text":"Abasi Abudulimu, Friedrich Sch\\\"oppler, Klaus H.
