Synthesis of O-N-S self-doped carbon quantum dots from a discarded football for Fe3+ detection

Abstract A discarded-waste football were served as a carbon precursor to built O-N-S self-doped carbon quantum dots (CQDs) by a hydrothermal route. The CQDs have strongly cyan luminescence, excellent stability, excitation wavelength-dependent, and etc, it could be found that the CQDs were acted as a fluorescent probe for the detection of Fe3+, exhibiting sensitivity and selectivity, which is of great significance for the effective monitoring of human health.
