Nitrogen doped carbon dots (N-CDs) have been prepared via a one-pot hydrothermal method by using formamide and o-phenylenediamine as the carbon precursors for Fe3+ and HPO42− detection.
Nitrogen-doped carbon dots (CDs) were synthesized through a hydrothermal process. The as-prepared CDs were used as fluorescent ink and sensors for the sensitive detection of temperature and Fe3+in aqueous solution.
