Understanding the reduced fluorescence of single-walled carbon nanotubes in water: the roles of dielectric screening and energy transfer to water vibrations
Abstract: Single-walled carbon nanotubes (SWCNTs) exhibit markedly weaker fluorescence in aqueous environments compared to dry or nonpolar conditions. This article explains two key mechanisms behind this quenching: (1) Coulomb screening by water’s high dielectric constant, which diminishes exciton binding energy, and (2) enhanced non-radiative relaxatio…
