Title: Ultrashort Carbon Nanotubes That Fluoresce Brightly in the Near-Infrared

Abstract

The intrinsic near-infrared photoluminescence observed in long single-walled carbon nanotubes is known to be quenched in ultrashort nanotubes due to their tiny size as compared to the exciton diffusion length in these materials (>100 nm). Here in this study, we show that intense photoluminescence can be created in ultrashort nanotubes (~40 nm length) upon incorporation of exciton-trapping sp3 defect sites. Using super-resolution photoluminescence imaging at <25 nm resolution, we directly show the preferential localization of excitons at the nanotube ends, which separate by less than 40 nm and behave as independent emitters. Lastly, this unexpected observation opens the possibility to synthesize fluorescent ultrashort nanotubes—a goal that has been long thought impossible—for bioimaging applications, where bright near-infrared photoluminescence and small size are highly desirable, and for quantum information science, where high quality and well-controlled near-infrared single photon emitters are needed.
