Abstract
Carbon dots are a new type of fluorescent carbon nanomaterials with the characteristics of photoluminescence,fluorescence stability,matt bleaching and good water solubility,etc,and are widely used in the fields of environmental monitoring,analysis and detection and photoelectric components.The preparation methods of fluorescent carbon dots,such as electrochemical synthesis,laser ablation,hydrothermal method,ultrasonic method,microwave method and template method,were introduced.The main reasons for fluorescence quenching of fluorescent carbon dots in the detection of heavy metal ions were analyzed.The application of fluorescent carbon dots in the detection of heavy metal ions was reviewed,and the future development direction was prospected.
