Citric acid triammonium is formed by Citric acid reacting with ammonia in a molar ratio of 1:3. It can be utilized as a carbon source for preparing carbon quantum dots (CDs). When citric acid triammonium contains higher nitrogen components, it may enhance the nitrogen-based functional groups in CDs, leading to more efficient emission-color tunability.
