“…Although there are numerous methods for the synthesis of R-CDs, hydrothermal and solvothermal methods, [28][29][30][31][32][33][34][35][36][37][38][39][40] remain the most common. One of the most striking examples is Liu et al, 41 who used a conjugated aromatic amine precursor (tris(4-aminophenyl) amine, TAPA) to prepare R-CDs with an emission wavelength at 615 AE 2 nm, a quantum yield (QY) of 84 AE 5%, and a full width at half maximum (FWHM) of 27 AE 1 nm, which is one of the highest levels of R-CDs to date.…”

“…Carbon dots (CDs), a kind of nanoparticles with a particle size less than 10 nm, have the advantages of good biocompatibility, high water solubility, a high fluorescence quantum yield, strong anti-bleaching ability, and an adjustable emission wavelength (Liu et al, 2019b;Qu et al, 2019;Qu and Sun, 2020;Yang et al, 2020). By improving the synthesis method or surface modification, CDs have been widely used in the detection of ions or small molecules (Liu et al, 2019a;Gong et al, 2019;Qi et al, 2019;Hu et al, 2021). Yang et al reported the detection of Fe 3+ with blue fluorescent carbon dots and investigated its detection mechanism (Song et al, 2014).…”

The chloride ion is an essential ion in organisms, which plays an important role in maintaining normal cell functions. It is involved in many cell activities, such as cell proliferation, cell excitability regulation, immune response, and volume regulation. Accurate detection of the chloride ion can balance its concentration in vivo, which is of great significance. In this study, we developed a green fluorescent carbon quantum dot to detect chloride concentration through the “off–on” mechanism. First, the fluorescence of carbon dots is quenched by the complex of sulfhydryl and silver ions on the surface of carbon dots. Then, the addition of chloride ions pulls away the silver ions and restores the fluorescence. The fluorescence recovery is linearly related to the concentration of chloride ions, and the limit of detection is 2.817 μM, which is much lower than those of other reported chloride probes. Besides, cell and zebrafish experiments confirmed the biosafety and biocompatibility of the carbon dots, which provided a possibility for further applications in bioimaging in vivo.

“…The detection limits for Cr 3+ and Pb 2+ were 27 nm and 34 nm, respectively. Hu et al [ 84 ] followed a solvothermal treatment of o-phenylenediamine and selenourea in HCl to synthesize red-emissive Se,N,Cl codoped C-dots with QY = 23.6%, the emission of which can be selectively quenched in the presence of malachite green (MG), thus functioning as nanosensors for MG with a limit of detection close to 20 nM.…”

Carbon dots (C-dots) represent an emerging class of nontoxic nanoemitters that show excitation wavelength-dependent photoluminescence (PL) with high quantum yield (QY) and minimal photobleaching. The vast majority of studies focus on C-dots that exhibit the strongest PL emissions in the blue/green region of the spectrum, while longer wavelength emissions are ideal for applications such as bioimaging, photothermal and photodynamic therapy and light-emitting diodes. Effective strategies to modulate the PL emission of C-dot-based systems towards the red end of the spectrum rely on extensive conjugation of sp2 domains, heteroatom doping, solvatochromism, surface functionalization and passivation. Those approaches are systematically presented in this review, while emphasis is given on important applications of red-emissive suspensions, nanopowders and polymer nanocomposites.
