@gigabecquerel by a weird coincidence we looked up this one late last night because we stumbled across a mention that when making carbon dots in this way, the fluorescence is due to citrazinic acid (6-hydroxy-2-pyridone-4-carboxylic acid) formed during microwaving, and it was the citrazinic acid we were researching

@gigabecquerel (oh, to be more precise: citrazinic acid is formed in microwave syntheses of N-doped carbon dots involving citric acid and urea)

@mxchara @gigabecquerel Is there an explanation of how the reaction forms the carbon dots etc from the simple starting points?
