Properties, synthesis, and applications of carbon dots: A review

     The paper of the day from Carbon Trends gives a vast overview of carbon dots, a type of zero-dimensional carbon-based nanoparticles with tunable physical, chemical, and optical properties. This review article covers top-down and bottom-up synthesis procedures, different properties, and vast applications of carbon dots. It also talks about carbon dots' relationship between structural and optical properties, their non-toxicity, biocompatibility, physical and chemical responsiveness, and their resistance to photo and chemical bleaching, which ultimately leads to a vast number of applications. Photoluminescence is an important property of carbon dots, so in this review, they have explained graphitic core-induced photoluminescence properties, surface-induced photoluminescence properties, and surface configuration-induced photoluminescence properties of carbon dots. In overall control over synthesis, photoluminescence, chemical stability, and dispersibility of carbon dots it can be greatly used in applications like LEDs, anticounterfitting, bioimaging, and sensing.
