利用飞秒激光辐照氧化石墨烯水悬浮液，成功合成了具有可调谐荧光发射的碳纳米颗粒。通过在氨分子存在下将氮掺杂到CNPs中，可以控制发光性质。我们还证实了具有金刚石结构的CNPs直接从溶剂分子如环己烷中沉淀出来。
Fluorescent Carbon nanoparticles (CNPs) with tunable emission are successfully synthesized from the water suspension of graphene oxide by the femtosecond laser irradiation. The luminescence properties were controllable by doping nitrogen into CNPs in the presence of an ammonia molecule. We have also confirmed that CNPs with diamond structure were directly precipitated from the solvent molecules such as cyclohexane.
