In an article published in the journal Molecules, researchers proposed a single change in the pH of the synthesis condition, which had no effect on the carbon dots (CDs) intrinsic core states and avoided the mutual influence of multiple photoluminescence (PL) origins.
The rapid growth of luminous carbon-based nanomaterials (carbon dots, CDs) during the last decade has been one of the most promising ways to create effective luminescence through simple synthesis. CPDs are being studied extensively as a new subclass of CDs. Then, there is the question of what is glowing and why is it shining.
