Carbon Nanodots: Preparation, Properties, Application (A Review)

Carbon nanodots are a special class of nanoparticles with a size of 1 nm, consisting mainly of carbon and having pronounced fluorescent properties. They have been discovered 20 years ago, and since then have found numerous applications as fluorescent sensors, photocatalysts, fluorescent inks, etc., which has led to the rapid development of methods for their production and study. This review summarizes modern ideas about the synthesis, isolation, optical properties and application of carbon nanodots. The main directions for further research in this area are formulated.
