Carbon quantum dots have attracted widespread attention as a rising star in nanocarbon in recent years. Since their discovery, people found many synthetic methods to derive carbon quantum dots, mainly including electrochemical, chemical, laser ablation and microwave. For their optical properties, water solubility, low toxicity, chemical inertness, low cost, CQDs have found many applications in many field, especially in catalysis, bioimaging, chemical sensing. Herein we describe the progress in the field of CQDs, focusing on their synthetic methods and applications.
