Discovered by accident while researchers were purifying carbon nanotubes in 2004, carbon nanodots (CNDs, or simply C-dots) are nanoparticles with sizes below 10 nm. Like fullerene, carbon nanotubes, and graphene, carbon nanodots are surface‐passivated carbonaceous quantum dots. They are typically composed of carbon, oxygen, nitrogen and hydrogen.
The relative amount present of each of these elements depends on the synthesis process used to create the carbon nanodots. Carbon dots can be synthesised from different approaches featuring bright fluorescent emission tuneable across the visible range, high water solubility with rich hydrophilic surface groups, biocompatibility, high sensitivity to the external environment, and marked electron donating and accepting capabilities.
Compared with other semiconductor nanodots with heavy metal cores, carbon nanodots have a number of distinct benefits including chemical inertness, low toxicity, ease of functionalization and resistance to photobleaching. Carbon nanodots are versatile and can be used in a wide range of technologies, such as bioimaging, photocatalysis, sensing, lasers, LED, and energy conversion/storage devices.
