Harnessing versatile dynamic carbon precursors for multi-color emissive carbon dots

Abstract

Carbon dots (CDs), a relatively new kind of fluorescent nanomaterials superior to other contributors of carbon allotrope due to their excellent biocompatibility, controllable photoluminescence, high quantum yield (QY), unique electronic...

Internal dual-emissive carbon dots for the double-signal detection of procainamide

“…The dyes belonged to a class of organic aromatic small molecules and possessed fluorescence units and abundant functional groups, so the formation of dual-colour carbon dots could be expected. 43 This method may have the potential to be expanded to the general preparation of dual-emissive carbon dots using other fluorescent dyes. In view of the IFE between the Y-CDs and PA, a new strategy for the fluorescent determination of PA was established.…”

Synthesis of Doped/Hybrid Carbon Dots and Their Biomedical Application

“…The purpose of S-doping in CDs is typically to enhance metal ion (Fe 3+ ions, other heavy metal ion) detection sensitivity by 0–500 µM [ 91 ]. However, if the S atom is fixed to the ring of polythiophene, strong red-emitting light can be observed when the excitation wavelength is 543 nm [ 92 ]. Further, the B/ N/S-co-doped CDs demonstrate high-efficiency red emission at wavelength near 600 nm [ 92 ].…”

Even though a variety of nonmetals, such as N, P, S, and B, have been reported, there is still a strong demand for the development of highly efficient CDs in term of real application for our society [ 92 ].…”

Therefore, further exploration of other nonmetal doping systems is highly desirable.…”

Towards two-dimensional color tunability of all-solid-state electrochromic devices using carbon dots

“…Consequently, it is a feasible strategy to design multi-color ECDs from the perspective of electrolyte layer ( Périé et al, 2022 ; Chang et al, 2018 ; Kanazawa and Uemura, 2019 ; Chan et al, 2021 ). As a fluorescent labeling material, carbon dots (CDs) can display various colors by controlling their concentration in organic solvents ( Wang et al, 2020 ; Ma et al, 2020 ; Wang et al, 2021 ; Wei et al, 2022 ). In this work, a novel concept for transparent inorganic multicolor ECD was successfully designed and fabricated by introducing CDs into the ion electrolyte layers.…”
