“…Thus, a simple, sensitive and selective flow-injection CL method was successfully established for detecting sulfide in the environmental samples. [82] Using the same KMnO 4 system, Zheng and coworkers [83] compared the influences of different functionalized CDs on the CL intensity. The results indicated that reduced state carbon dots (r-CDs, possessing many hydroxyl groups) could react more easily with KMnO 4 and increase the CL intensity much higher than simple CDs due to the different functional groups on these two kinds of CDs.…”

In recent years, more and more nanomaterials‐based chemiluminescence (CL) systems have appeared to improve the sensitivity and expand the scope of the analytical applications with the explosive growth and development of nanomaterials and technology. As a fascinating class of luminescent carbon nanomaterials, carbon dots (CDs) are now substantially studied in fabricating CL based assays due to their unique optical and mechanical properties. Herein, we summarize and highlight the current developments of CDs‐involved weak or ultraweak CL systems, as well as the corresponding mechanisms and proper applications in some fields. CDs can take part in the CL reactions as oxidants, emitting species directly involved in redox oxidation, energy acceptors of CL energy transfer, or even catalysts involving other luminophores. In fact, they always have more than one role in many cases, owing to the formation of various excited species with short life in CL systems. Therefore, in this review article, the most recent progress of the different CDs‐assisted CL systems including the mechanisms and applications are presented. Finally, the conclusions and future prospects of this field are also discussed. The significant features of the CDs‐based CL systems may open up new prospects and challenges in a wider range of fields.

Summary Carbon quantum dots (CQD) and graphene quantum dots (GQDs) have been mentioned frequently. They have been selected in recent studies as they have unique and remarkable potential, especially in electrical, optical, and optoelectrical properties. CQD and GQDs have very high chemical and physical stability due to inherent inert carbon material, thus newly recognized as a kind of quantum dots material. Its environmentally friendly, non‐toxic, and naturally inactive nature is also a major attraction for scientists around the world. In this work, CQD and GQDs production methods are discussed in detail, including soft‐template method, hydrothermal method, microwave‐assisted hydrothermal (MAH) method, metal‐catalyzed method, liquid exfoliation method, electron beam lithography method, and others. Additive material has been introduced in CQD and GQDs to increase the ability and performance of CQD and GQDs such as nitrogen, sulfur, chlorine, fluorine, and potassium. In particular, the presence of additive material in CQD and GQDs shows an advantage in terms of energy level, which is very good at achieving specific requirements in properties such as optical, electrical, and optoelectrical. In addition, the existence of functional groups consisting of heteroatoms such as oxygen, nitrogen, sulfur, phosphorus, boron, and so on of zero‐dimensional carbon materials in providing an overabundance of the active electrochemical site for the reaction. The product of CQD and GQDs has various shapes and sizes influenced by several parameters such as synthesis temperature, growth time, source concentration, catalyst, and so on. The application of CQDs and GQDs composites in fuel cells has been clearly and scientifically stated as it has enhanced the performance of fuel cell technology.
