The emerging hetero-atom doped carbon-based quantum dots have been attracting attention because of their tremendous potential for electro-chemical, optoelectronic and biomedical applications, which is due to their tunable optical properties using simple functionalization. Here, we report a facile one-step synthesis of nitrogen (N) doped high-crystalline graphene quantum dots (N-GQDs) using top-down and bottom-up approaches. An interesting property of nGQDs can be simply controlled by synthetic conditions with different N contents. This finding indicates that our approach could lead to low-cost and efficient processability that is scalable and environmentally friendly. We believe that the shape, size and functionality of these GQDs can be controlled using other chemical species to provide a variety opportunities for use in opto-electronics, biological applications and sensors. |
