dc.description.abstract | Fluorescent carbon dots (CDs) have motivated a significant amount of research because of their properties such as excellent biocompatibility and low toxicity. In this work, water-soluble fluorescent CDs were synthesized from celery stalks by a one-step, low-cost hydrothermal process. The as-prepared CDs had the average size of 3.7 +/- 1.1 nm, and they emitted bright blue photoluminescence. The surface functional groups and states were investigated via Fourier-transform infrared spectroscopy and X-ray photoelectron spectroscopy. The blue fluorescence of the as-prepared CDs was effectively quenched by Cu2+ ions compared to other competing metal ions. Therefore, these CDs are promising probes for the fluorescence detection of Cu2+ ions. Moreover, an excellent linear relationship was obtained between the relative fluorescence intensity and the concentration of Cu2+ ions in the linear detection range 0-100 mu M, and the limit of detection was 0.132 mu M. | - |
