“…Research studies have shown that the fluorescent signal and photoelectrical performance of CDs can be greatly enhanced after surface passivation or doping. 38 Herein, based on the different doped species, the CDs are divided into five types, namely, undoped CDs, metal-doped CDs, nonmetal-doped CDs, co-doped CDs and CD nanocomposites.…”

“…CDs have unique properties such as good luminescence, excellent photostability, good water dispersibility, low toxicity, and biofriendliness, making them one of the most promising fluorescent materials. Fluorescent CDs, therefore, have been widely used in biomedical, 3 printing anti-counterfeiting, 4,5 environmental detection, 6 bioanalysis, and catalytic sensing. 7,8 Owing to these unique properties and various applications, fluorescent CDs have been developed in various ways, for example, an electrochemical oxidation method, 9 solvothermal method, 10 template method, and microwave method.…”

As a type of carbon-based nanomaterial, the most prominent feature of carbon dots (CDs) is their fluorescence properties. In this work, blue, green, and red water-dispersible CDs with trichromatic properties were prepared by a microwave method using corn starch, citric acid, p-phenylenediamine, and urea. The emission wavelengths of the CDs at the same excitation wavelength were 423, 524, and 621 nm, respectively. The morphological characteristics and optical properties of the three CDs were characterized, and the mechanism that drives the specific color of CDs was analyzed. The experimental results showed that white fluorescence with CIE color coordinates of (0.33, 0.34) and a series of tunable fluorescent colors could be obtained by adjusting the mixing ratio of blue, green, and red CDs, and multicolor polyvinyl alcohol fluorescent films were synthesized using CDs as pigments. At the same time, the printing effect was realized by an inkjet printer.

“…Boron and nitrogen are doped into CQDs to generate P-type CQDs (with excess holes) and N-type CQDs (with excess electrons), respectively . The physical and chemical properties of CQDs could be changed by heteroatoms. , Therefore, the fluorescence behavior of boron-doped or nitrogen-doped CQDs as well as the selectivity and sensitivity to specific analytes might be different from those of traditional CQDs, which might expand the applicability of CQD sensing for various types of targets. − …”

A facile and cost-effective hydrothermal method was developed for the preparation of boron and nitrogen codoped carbon quantum dots (B,N-CQDs) from 3-carboxyphenylboronic acid and o-phenylenediamine. The synthesized B,N-CQDs exhibit excellent properties such as excellent water solubility, strong fluorescence, good dispersion, and desirable stability. The average particle size of B,N-CQDs is 2.82 nm, and the absolute fluorescence quantum yield is 86.58%. The excitation wavelength of B,N-CQDs is 300 nm. Emission bands of B,N-CQDs appeared at 356 and 700 nm. Periodate (IO 4 − ) quenches B,N-CQDs emissions through chelation reaction. The ratio of F 356 / F 700 has a good linear relationship with the concentration of IO 4 − in the range of 0.01−40 μmol/L with the detection limit of 0.003 μmol/L. This method has the advantages of a low detection limit, high sensitivity, wide linear range, good selectivity, simplicity, and rapidness. It can be used as a ratiometric fluorescent probe for the detection of IO 4 − , and it was successfully applied in the analysis of IO 4 − in water. The cytotoxicity and biocompatibility of B,N-CQDs were evaluated and successfully applied in cell imaging.
