One-step synthesis of fluorescent carbon nanoparticles by laser irradiation

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

“…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].…”

Hydrogen peroxide sensing based on carbon quantum dots

“…Compare to semiconductor quantum dots, luminescent CQDs were considered as a brand new class of luminescent due to their small size, high quantum yield, low cytotoxicity, possess fine biocompatibility, high photostability and environment friendliness, which make them suitable chemical and biological analyses. There are several methods to prepare CQDs have been reported [13][14][15][16][17]. However, these methods usually require not only complicated equipment and expensive materials but also complicated post treatment to enhance the quantum yield and water solubility of CQDs.…”

Fluorescence Determination of Glutathione Using Tissue Paper-derived Carbon Dots as Fluorophores

“…16 Currently, various methods like chemical ablation, 17 electrochemical carbonization, 18 laser ablation, 19 microware irradiation 20 and hydrothermal/solvothermal treatment 21 have been used for the synthesis of CDs. Among these, microwave irradiation technique stands out due to its advantages, like increased reaction rates, uniform heating, improved product yields, broad dynamic temperature range and environment friendly nature.…”
