“…Thus, if a boron atom is introduced in a carbon cluster, p-type carriers are generated inside C-dots, changing their electronic structures and optical properties. 106,[131][132][133][134] Shan et al reported that fluorescent B-doped carbon quantum dots were prepared by a facile one-pot solvothermal route using BBr 3 as the boron source and hydroquinone as the carbon source 131 (Fig. 11).…”

“…Han et al synthesized B,N-doped C-dots by a combustion flame technique, using boric acid and pyrrole as precursors. 106 The B,N-doped C-dots have a maximum emission wavelength of 524 nm, and exhibit excitation-independent PL behavior. The as-prepared B,N-doped C-dots show high catalytic activity in the oxygen reduction reaction (ORR), comparable to that of commercial Pt/C.…”

Distinct from conventional carbon nanostructures, such as fullerene, graphene, and carbon nanotubes, carbon nanodots (C-dots) exhibit unique properties such as strong fluorescence, high photostability, chemical inertness, low toxicity, and biocompatibility. Various synthetic routes for C-dots have been developed in the last few years, and now intense research efforts have been focused on improving their functionality. In this aspect, doping and surface functionalization are two major ways to control the chemical, optical, and electrical properties of C-dots. Doping introduces atomic impurities into C-dots to modulate their electronic structure, and surface functionalization modifies the C-dot surface with functional molecules or polymers. In this review, we summarize recent progress in doping and surface functionalization of C-dots for improving their functionality, and offer insight into controlling the properties of C-dots for a variety of applications ranging from biomedicine to optoelectronics to energy.

“…Hence, synthesis of quantum dots with excellent fluorescence and good biocompatibility is remains as a big challenge. To overcome this issue researchers also attempted to formulate non‐heavy metal and non‐metal quantum dots ,. However, limited their use due to physicochemical properties and poor fluorescence behavior.…”

Here, we report the use of the chemically modified one-step facile hydrothermal process to develop Boron (B), Nitrogen (N), and Phosphorous (P) doped carbon dots (E@CDs). The chemical characterization of the E@CDs was systematically studied by several analytical techniques that confer doping of elements by known characteristics. The obtained E@CDs had observed very homogeneous size distribution and displayed excitation dependent fluorescence properties, and high quantum yield (QY) was measured in case of B and N doping. Excellent cell viability and good cellular uptake was observed for all E@CDs. Finally, E@CDs were compared with pristine CDs on their effect on cell labelling, neural differentiation process and outgrowth of neurite network. By manipulating the doping of CDs, we can control the branching pattern and outgrowth of neuronal developments. The E@CDs are capable due to their photostability biocompatibility, and possible selective affinity towards nanomedicine applications.[a] Dr.

Despite the various synthesis methods to obtain carbon dots (CDs), the bottom‐up methods are still the most widely administrated route to afford large‐scale and low‐cost synthesis. However, as CDs are developed with increasing reports involved in producing many CDs, the structure and property features have changed enormously compared with the first generation of CDs, raising classification concerns. To this end, a new classification of CDs, named carbonized polymer dots (CPDs), is summarized according to the analysis of structure and property features. Here, CPDs are revealed as an emerging class of CDs with distinctive polymer/carbon hybrid structures and properties. Furthermore, deep insights into the effects of synthesis on the structure/property features of CDs are provided. Herein, the synthesis methods of CDs are also summarized in detail, and the effects of synthesis conditions of the bottom‐up methods in terms of the structures and properties of CPDs are discussed and analyzed comprehensively. Insights into formation process and nucleation mechanism of CPDs are also offered. Finally, a perspective of the future development of CDs is proposed with critical insights into facilitating their potential in various application fields.
