利用激光照射有机溶剂中的碳粉悬浮液，合成了荧光碳纳米颗粒。碳纳米粒子的表面修饰是在碳纳米粒子形成的同时进行的，通过选择合适的溶剂可以产生可调谐的发光。发光的起源归因于碳纳米管表面的羧基配体。
Fluorescent carbon nanoparticles (CNPs) were synthesized by laser irradiation of a suspension of carbon powders in organic solvent. The surface modification on the CNPs was fulfilled simultaneously with the formation of the CNPs, and tunable light emission could be generated by selecting appropriate solvents. The origin of the luminescence was attributed to carboxylate ligands on the surface of the CNPs.
