“…[114] A ratiometric fluorescence nanohybrid (CSCDs@DC) was designed by Yin Xueqiong et al by grafting dansyl fluorophore (DC) onto N-doped CDs (CSCDs) at room temperature. [115] SEM data showed that CSCDs were covered by DC, and larger particles were apparently formed. Under an excitation of 330 nm, the CSCDs@DC aqueous solution showed dual fluorescence emission peaks at 412 nm and 500 nm.…”

It is very appealing to develop cheap, highly sensitive and efficient metal ion fluorescence sensors as traditional instrument methods are inherently costly and time‐consuming. Carbon dots (CDs) are widely used for sensing metal ions, attributing to their merits of good biocompatibility, low toxicity, easy surface modification and excellent photostability. This article reviewed the research progress of CDs as metal ion sensors in recent years, and studied their modification methods and detection performances. Finally, the challenges and opportunities of CDs as metal ion sensors were also analyzed. This article is expected to provide inspiration and help for researchers focusing on CDs as metal ion sensors.

“…The sensor was tested with real samples of tap water and orange juice, proving to be practical and effective [97]. Recently, several other studies on the fluorescence sensors based on doped CDs have been reported using different carbon sources, such as chitosan and dansyl [72], maize starch [73], citric acid and L-cysteine [74], trisodium citrate and phosphoric acid [75], benzene sulfonic and phenylboronic acid derivatives [76], etc. A brief description of these studies is provided in Table 1.…”

The design of nanomaterials for application in diverse fields ranging from photovoltaic to fluorescence sensing is a research area of increasing interest. Recently, Quantum Dots (QDs), which are classified as semiconductor quantum dots (SQDs) and Carbon dots (CDs), have become a hot topic of investigation, owing to their extraordinary tunable fluorescence emission properties that render them excellent candidates for sensing metal ions. The detection of metal ions in aqueous solutions with high sensitivity is very important as these ions have toxicological and environmental impacts. In this short review, we have described the fluorescence emission properties of CDs and their application for the detection of different metal ions, such as Hg2+, Pb2+, Cu2+, Fe3+, Cd2+, and Cr6+.

In this study, rose bengal‐derived carbon quantum dots (RB‐CQDs) was synthesized by a one‐step solvothermal method using rose bengal and 1,2‐phenylenediamine as precursors in ethanol at 180 °C for 10 h and purified by silica gel chromatography. The as‐synthesized RB‐CQDs disperses well in water with particle sizes ranging from 0.78 to 2.46 nm and exhibits excitation‐independent yellow fluorescent emission (529 nm), high quantum yield (44.3 %) and good biocompatibility. More importantly, the fluorescence of RB‐CQDs can be selectively quenched by Fe3+ ions with good linear correlation and the detection limit is 19.9 nM. The recoveries of this method in actual water samples are 90 % to 110 % with relative standard deviations less than 5 %.
