Carbon dots have drawn extensive attention in the detection of metal ions with good stability, excellent biocompatibility and low toxicity. Meanwhile, quantum yield, response rate mechanism for Cu2+ are vital to their development application. To obtain more selective sensitive materials detect ions, N-doped carbon (DN-CDs) were synthesized by a one-step hydrothermal method using citric acid as source diethylenetriamine (DETA) nitrogen source. The obtained DN-CDs exhibited stable intense blue light emission special near-infrared up-conversion fluorescence at 820 nm, attributed effect introducing N atoms into structure dots. Due dynamic quenching intensity (λex = nm) was quantitatively decreased presence ions. had rapid within 3 min. DN-CD system linear relationship concentration range from 2.5 50 µM limit (LOD) 42 nM. After careful investigation, an interesting conclusion proposed: CDs N/O 1:1 or higher relatively abundant prefer while those 1:2 lower Fe3+

A facile synthesis method involving a one-step solvothermal is demonstrated in producing fluorescent nitrogen-doped carbon dots (N-CDs) by employing biomass waste (Jengkol peels) and ethylenediamine as source for nitrogen. The synthesized N-CDs are spherical nanoparticles with an average size of 4.495 nm, exhibit solubility water, emit bluish-green fluorescence high quantum yield up to 42%. By using UV–Visible, FTIR, XPS, HR-TEM Photoluminescence analysis, the as-prepared were verified. We demonstrate that nitrogen doping increases emission intensity its radiative recombination π − π∗ transitions at CC n CO or CN. optimized excitation 370 exhibited strong PL 522 nm.
