Carbon Dots from Citric Acid and its Intermediates Formed by Thermal Decomposition.

Robert Ludmerczki et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 25(51), 11963-11974 (2019-06-30)

Thermal decomposition of citric acid is one of the most common synthesis methods for fluorescent carbon dots; the reaction pathway is, however, quite complex and the details are still far from being understood. For instance, several intermediates form during the
