“…Raman spectra of C-dots usually present two main first-order bands [3,27,32,41,88,129,[144][145][146][147][148][149]. The D band represents the vibrations of carbon atoms with dangling bonds in the termination plane of disordered graphite or glassy carbon.…”

Carbon nanodots (C-dots) are recently discovered fluorescent carbon nanoparticles with typical sizes of <10 nm. The C-dots have been reported to have excellent photophysical and chemical characteristics. In recent years, the advances in the development and improvement in C-dots synthesis, characterization, and applications are burgeoning. In this review, we introduce the most commonly used techniques for the characterization of C-dots. The characterization techniques for C-dots are briefly classified, described, and illustrated with applied examples. In addition, the analytical separation methods for C-dots (including electrophoresis, chromatography, density gradient centrifugation, differential centrifugation, solvent extraction, and dialysis) are included and discussed according to their analytical characteristics. The review concludes with an outlook towards the future developments in the characterization and the analytical separation of C-dots. The comprehensive overview of the characterization and the analytical separation techniques will safeguard people to use each technique more wisely.

“…However, the large scale preparation and surface passivation of C-dots are still expected to provide highly fluorescent C-dots by using economical and facile approaches. Up to now, various carbon sources have been used to prepare C-dots such as laser ablation of graphite [19,20], electrochemical treatment of graphite [21], commercial activated carbon by bottom-up method [9], heating carbohydrate, watermelon peels or PEG with microwave pyrolysis [22][23][24]. The prepared C-dots are highly water-soluble, nano-sized and multi-colourful.…”

“…Because of these features, various methods for fluorescent CNP synthesis have been reported by using carbon-based materials as carbon resources. [14,19,20] For example, top-down methods include laser ablation of carbon powder [14], electrochemical oxidation [21] and arc discharge [22]; bottom-up methods consist of microwave synthesis, [23,24] combustion soots of candles, [25,26] thermal oxidation of carbon precursor by employing silica or zeolites as carriers [27,28] commercial activated carbon [29], lampblack [30] and watermelon peel as carbon resources [31]. All these methods suffer to some degree from drawbacks like tedious processes, harsh synthetic conditions or expensive starting materials.…”
