| Abstract: We used the natural product chamomile as a carbon source to synthesize praseodymium(Pr) and nitrogen (N) co-doped biomass carbon dots (Pr/N-BCDs) with remarkable luminescence properties by one-step hydrothermal method. Compared with single N doped BCDs (N BCDs) and Prdoped BCDs (PrBCDs), Pr/N BCDs not only showed better fluorescence properties and stability but also achieved a significant increase in quantum yield of 12%. More importantly, under certain conditions, Pr/N-BCDs and 2,4-dinitrophenylhydrazide (2,4-DNPH) had significant fluorescence internal filtration effect (IFE) and dynamic quenching effect, and in the concentration range of 0.50-20 μmol·L-1, the concentration of 2,4-DNPH had a good linear relationship with the fluorescence quenching signal, and the detection limit was as low as 2.1 nmol·L-1. |
