Fluorescent carbon quantum dots from Syzygium aromaticum as a selective sensor for Fe3+ and Cd2+ detection in aqueous solution

Fluorescent carbon quantum dots (SA-CQDs) from Syzygium aromaticum were synthesized via carbonization-assisted ultrasonication, exhibiting an average size of 3.314 nm and strong blue fluorescence at 440 nm (excitation: 350 nm) with a quantum yield of 12.61 %. FTIR and UV–vis confirmed oxygen-contain...
