| Research Abstract |
Nano-carbon materials such as carbon nanotube, graphene, have intriguing electronic and optical properties. In this study, we studied the quantum optical properties of nano-carbon materials toward novel functionalites. We obtained the results, 1) first observation of negative charged exciton (trion) in carbon nanotube by electrochemical doping technique, 2) revealing spatial localization trion with 0-dimensional characteristics, 3) drastic enhancement of photoluminescence quantum yield up to 18%.
