Surface Functionalized Carbogenic Quantum Dots

Study on fluorescence properties of carbogenic nanoparticles and their application for the determination of ferrous succinate

“…This size was much smaller than that reported in E.P. Giannelis' work (near 7 nm) [13]. Although in both works carbogenic NPs were prepared with the same materials and pyrolytic method, the reaction temperatures were different, which were 300 and 250 1C, respectively.…”

“…Carbogenic NPs based on citrate precursor were prepared via the procedure described by Bourlinos et al [13] with some slight modifications. Briefly, citric acid monohydrate (1 g, 4.75 m mol) was dissolved in water (5 mL) and OHCH 2 CH 2 OCH 2 CH 2 NH 2 (0.65 g, 6.2 mmol) was added.…”

“…The particles were called ''carbogenic'' because they were not of pure carbon composition like carbon nanotubes or carbon nanodiamond but proved to be oxygen-containing carbon dots. Fluorescent carbogenic NPs can be obtained by various methods such as laser ablation of graphite [4,5] or carbon powders [6], proton-beam irradiation of nanodiamonds [7,8], carboxylation of carbon nanotubes [9][10][11], electrooxidation of graphite [12], hydrothermal decomposition of ammonium citrate salts [13,14] or separating from candle soot [15].…”

Laser assisted synthesis of carbon nanoparticles with controlled viscosities for printing applications

“…Topdown strategies include electrochemical synthesis [6], laser ablation [7], and arc discharge [8]. Bottom-up strategies include ultrasonic methods [9], microwave assisted synthesis [10], and hydrothermal treatment [11].…”

Production of yellow-emitting carbon quantum dots from fullerene carbon soot

“…These methodologies can be mainly classified into two categories, namely, the "top-down" and "bottom-up" methods. The former includes laser ablation [12][13][14], plasma treatment [15], electrochemical oxidation [16][17][18][19], and acid-refluxing [20][21][22][23][24][25][26][27][28][29][30][31], while the latter is mainly focused on pyrolysis using simple heating and hydrothermal or microwave treatment [32][33][34][35]. Among these methods, the acid-refluxing of raw carbon materials offers a large-scale production of CQDs as it only needs simple instruments and can be easily scaled-up using standard industrial equipment.…”
