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.
A green, simple and low-cost approach was present to obtain N-doped C-dots using vegetables as the sole carbon source through facile one-pot hydrothermal treatment. The C-dots can serve as a suitable sensing platform for detection of Cu2+.
A facile one-pot method is used to synthesize and self-assemble nanofibril cellulose hydrogels with carbon dots as intensity enhancement and fluorescent emission factors.
