Synthesis and characterization of high fluorescent engineered carbon dots

The utilization of microwave technology enabled the synthesis of high-purity fluorescent engineered carbon dots from citric acid and urea. The proposed procedure of producing carbon dots is efficient and environmentally due to high fluorescence production. Carbon dots are mostly made up of tiny size and multilayer graphene oxide, which has exceptional optical and fluorescence properties. To investigate the effects on carbon dots properties, UV–vis, fluorescence, FTIR and XPE spectroscopy were used. The successfully produced carbon dots that are excellently photo-stable and have excellent environmental stability. Fluorescence can be enhanced without passivating the surface. As a result of their obvious applications in cellular imaging, biosensing, light emitting diodes, supercapacitors, solar cells and printings, carbon dots and their functionalized nanocomposites have attracted much attention.
