  Carbon quantum dots   (CQDs) are a newly discovered class of quantum materials that have generated significant interest in both academia and industry. With a diameter below 10 nm, they are a type of carbon nanoparticle that exhibits remarkable physical and chemical properties. They range from simple organic molecules to complex functionalized materials and can be synthesized in various ways, making them an attractive candidate for a wide range of applications. Introduction of Carbon Quantum Dots Carbon quantum dots are zero-dimensional nanoparticles made of sp2-hybridized carbon atoms. They have a unique electronic structure that provides them with unique optical and electronic properties. Carbon quantum dots can be obtained from various carbon sources, such as graphite, graphene, carbon nanotubes, and organic materials such as vegetable oil, citric acid, pyrene, and others. Due to their size and unique structure, these materials have a large surface-area-to-volume ratio, ma...
