Electrochemical Preparation of Color-Tunable Fluorescent Carbon Quantum Dots

Aggregation Kinetics and Self-Assembly Mechanisms of Graphene Quantum Dots in Aqueous Solutions: Cooperative Effects of pH and Electrolytes

“…Graphene quantum dots (GQDs), one novel species of ultrasmall graphene-based nanomaterials that possess exceptional physical and chemical properties, have inspired intensive research efforts since being synthesized very recently. − They are classified as a zero-dimensional graphitic nanomaterial with lateral dimensions of less than 100 nm in a single to a few layers. , GQDs can be viewed from a dimensional perspective as a scaled down version of graphene oxide (GO) , and also as an enlargement of benzene-based molecules, i.e., polycyclic aromatic hydrocarbons (PAHs). − Correspondingly, these types of nanoparticles (NPs) are generally derived through top-down nanocutting methods , and bottom-up organic synthesis routes . The surface morphology and edge oxygen-containing groups can be further modified to gain controllable characteristics. − Emerging as superior and environmentally friendly functional materials, GQDs are attracting increasing attention in various research areas of environmental, biological, and energy-related applications. − …”

Carbon quantum dots modified and Y3+ doped Ni3(NO3)2(OH)4 nanospheres with excellent battery‐like supercapacitor performance

“…Figure 2d shows the emission spectra of the as‐prepared CQDs solution excited at 470 nm. Because the fluorescence property is a typical characteristic of CQDs, the broad peak centered near 570 nm can prove the formation of the CQDs [19] …”

“…Because the fluorescence property is a typical characteristic of CQDs, the broad peak centered near 570 nm can prove the formation of the CQDs. [19] Figure 3 shows the N 2 adsorption-desorption isotherms and pore size distribution of the NiY0, NiY, and NiY@CQDs. Table 1 lists the BET-specific surface area, pore volume, and pore size of the three materials.…”

DNA Binding and Cleavage Studies of Dichlorido[Bis(2-Ethyl-5-Methyl-1H-Imidazol-4-yl-κN3)Methane]Cobalt(II) Monohydrate

“…These spectroscopic features suggest that some EB molecules were released into solution after an exchange with the complexes which result in the fluorescence quenching of EB. These observations are often the characteristic of intercalation [25]. The complex-caused fluorescence quenching curves of EB-DNA are shown in Fig.…”
