Hydrothermal synthesis of B, S, and N-doped carbon quantum dots for colorimetric sensing of heavy metal ions

Abstract

CQDs were synthesized using glucose as the C source, and N-CQDs, B-CQDs, and S-CQDs were synthesized by doping with N, B, and S atoms. The colorimetric sensor properties of the synthesized CQDs for the detection of heavy metals were examined.
