The emerging carbon-based quantum dots have been attracting attention because of their tremendous potential for optoelectronic and biomedical applications, which is due to their unique and size-tunable optical properties, their ability to be functionalized, and their- biocompatibility. Here, we report the facile one-step synthesis of highly fluorescent and amphiphilic n-doped graphene quantum dots (N-GQDs) using a fumaronitrile precursor. An interesting property of the prepared N-GQDs is their near pH neutral dispersibility without refinement, which stands in contrast to reported method. 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.
