Graphene quantum dots (GQDs) are recently discovered carbon-based materials that correspond to nano-fragments of functional graphene-like structures. They could be synthesized either by conventional stepwise organic synthesis or, more rapidly, by either top-down or bottom-up one step approaches. Regardless of the synthetic route, GQDs display photoluminescence features (fluorescence and/or phosphorescence) that could be finely tuned according to their surface and edges chemistry. This makes this new organic material highly valuable in applications ranging from imaging, sensing and optoelectronics.

石墨烯量子点：新兴的有机材料，具有出色的可调发光特性

石墨烯量子点（GQD）是最近发现的碳基材料，与功能性石墨烯状结构的纳米片段相对应。它们可以通过常规的逐步有机合成法合成，也可以通过自上而下或自下而上的一步法合成。无论采用哪种合成途径，GQD均显示出可根据其表面和边缘化学性质进行微调的光致发光特征（荧光和/或磷光）。这使得这种新的有机材料在成像，传感和光电等应用中具有很高的价值。
