| Résumé | The semiconducting single walled carbon nanotube (s-SWNTs) with its direct bandgap and its strong 1D character absorbs and emits light efficiently. In contrast with other nanomaterials, the structure of an SWNT is uniquely defined and is set by a discrete number of carbon rings along its tubular section. Experimentally, optical spectroscopy has recently revealed this remarkable quantization. In our group, we focus primarily on the luminescence properties of individual s-SWNTs. Using imaging techniques, we reveal unambiguously that each s-SWNT with its quantized structure is characterized by a specific manifold of excitonic states. With the large diameter tunability achieved in SWNTs, we show that the material represents a model system for 1D photophysics. This proceeding is meant to be a review of past work and includes complementary data that have been presented at conferences but otherwise have never been published. Some emphasis is given on experimental details for luminescence imaging and spectroscopy. © 2011 SPIE. |
