“…However, the quenching effect by Cu 2+ might be interfered by some other metal ions, such as Fe 3+ , Fe 2+ , Hg 2+ . There are some other works about the detection of Cu 2+ based on various CDs [96,136,137,238]. In general, the detection mechanisms are similar to those mentioned above.…”

Carbon based dots (CDs) composed of sp 2 carbon structures and surface functional groups are a new kind of carbon nanomaterials, exhibiting unique luminescent properties due to the quantum confinement and edge effects. This chapter introduces CDs in detail from their synthetic strategies, morphological and structural characteristics, luminescent properties and mechanisms, and sensing applications. The synthesis methods are summarized as "top-down" and "bottomup" approaches. Luminescent properties discussed include photoluminescence, upconversion luminescence, chemiluminescence, electrochemiluminescence. Sensing applications mainly refer to the chemical and biological sensors based on the luminescent properties of CDs. This chapter provides an overview of the research field and gives future perspectives for developing the exciting materials.

“…(a). The UV absorption spectra of aqueous CDs solution show two characteristic absorption bands; a relatively small absorption band attributed to the π‐π * transition of electrons in aromatic moieties at 234 nm and a broad peak at 332 nm corresponding to n ‐π * of C=O transition . The broad peak at 332 nm in the UV absorption spectra of the carbon appeared due to trapping of large extent of excitation energy leading to huge amount of emission at 360 nm excitation .…”

Highly fluorescent nitrogen and phosphorus-doped carbon dots with a quantum yield 59% have been successfully synthesized from citric acid and di-ammonium hydrogen phosphate by single step hydrothermal method. The synthesized carbon dots have high solubility as well as stability in aqueous medium. The as-obtained carbon dots are well monodispersed with particle sizes 1.5-4 nm. Owing to a good tunable fluorescence property and biocompatibility, the carbon dots were applied for intercellular sensing of Fe(3+) ions as well as cancer cell imaging.

“…By using this equation, the grain sizes of C-dots and F-C-dots were determined to be 11 nm and 7.3 nm, respectively. Herein, it should be noted that although RS technique is powerful in the characterization of C-dots, several reports stated the difficulty [150] or failures [52,151,152] in acquiring a high-quality RS of C-dots sample due to the intense fluorescence of C-dots, resulting in covering the characteristics of the Raman signal.…”

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.
