Quantum control toward nano-carbon photonics in nano-carbon materials

纳米碳材料如碳纳米管、石墨烯等具有独特的电学和光学性质。本论文主要研究纳米碳材料的量子光学性质。结果表明：（1）电化学掺杂技术首次在碳纳米管中观察到带负电荷的激子（trion）;（2）trion空间局域化，具有0维特征;（3）光致发光量子产率显著提高，最高可达18%。

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%.
