The carbon quantum dot (CQD) paper-based analytical device (PAD) has drawn great attention and is being intensively explored. However, the construction of a continuous flow CQD synthesis remains challenging. In this work, reaction apparatus was constructed to synthesize nitrogen-doped CQDs using mixed-solvent system tetraethylene glycol water. optical properties were characterized. found be que...
