本次通讯提出了一种制备碳量子点的简单方法，即在普通有机溶剂中激光快速钝化纳米碳颗粒。所制备的碳点表现出可见、可调且稳定的光致发光（PL）。 XPS分析表明氧浓度的增加可能与PL的来源有关。
A simple approach to prepare carbon quantum dots is presented in this communication by laser rapid passivation of nano carbon particles in ordinary organic solvent. The as-prepared carbon dots exhibited visible, tunable and stable photoluminescence (PL). XPS analysis showed that the increased oxygen concentration might be concerned with the origin of PL.
