In our prior work we hypothesized that our emissive heterostructures relied on long-range exciton transport in the NPL followed by near unity energy transfer to the QD. We based this supposition by considering the average lateral lengths of the NPLs (~500 nm), the apparent high quantum yield of the emissive heterostructures (> 30% at the QD bandgap accompanied by complete quenching of the NPL emission), and the extremely low number density of QDs contributing to the absorption cross-section. These results qualitatively implied that excitons must be sampling a large area of the NPL before being quenched by transfer into "rare" QD on the surface.
