Abstract In recent years，carbon quantum dots（CQDs）as a new type of carbon nanomaterials have attracted
widespread attention. In addition to unique and excellent optical properties，CQDs also have good water solubility，
biocompatibility，low toxicity，and low cost. Since the discovery of CQDs，people have develop a variety of
synthesis methods，such as template method，microwave method，hydrothermal method，magnetron thermal
method，etc.，and because of its excellent properties，they have been widely used in biology，environment，energy，
and related material fields. The synthesis route，main properties of CQDs，and its applications and prospects
in energy，electronics and biological materials were clarified.
