| Abstract | Efficient synthesis and controlled modification of carbon dots (CDs) with tuneable properties on the basis of facile technical routes are of great significance for user-defined applications as well as more insightful understanding of the unique fluorescence from carbon nanomaterials. In this work, we report an improved nitric acid oxidization method towards low-cost and rapid preparation of fluorescent CDs. This is achieved by using industrial carbon black specimens as the precursor and implementing a reduced pressure distillation for the purpose of eliminating excessive acids. Unexpectedly, the product exhibits an interesting dual luminescence behaviour with tuneable characteristics that differs from all previously reported CDs. The strongest emissions at fixed or varied excitations can be simultaneously tuned from blue to green or yellow by simply prolonging the time of acid oxidization. These emissions show distinct stabilities in acid and alkaline environments, thereby making the resultant CDs very promising candidates for pH probes. It is further revealed that this simple synthesis and fluorescence tuning strategy is also applicable to CDs from other carbon blacks. |
