Citric acid triammonium
Based on 8 publication(s) in Google Scholar
Citric acid triammonium (Triammonium citrate) is formed by Citric acid (HY-N1428) reacting with ammonia in a molar ratio of 1:3. Citric acid triammonium can be used as the carbon source to prepare carbon quantum dots (CDs). Citric acid triammonium with higher nitrogen components might promote the nitrogen-based functional groups in CDs, leading to a more efficient emission-color tunability.
