High Efficiency Dark-to-Bright Exciton Conversion in Carbon Nanotubes
We report that dark excitons can have a large contribution to the emission intensity in carbon nanotubes due to an efficient exciton conversion from a dark state to a bright state. Time-resolved photoluminescence measurements are used to investigate decay dynamics and diffusion properties of exciton...
