摘要:碳量子点（CQDs）作为一种新型的零维荧光纳米材料，其具有优异的水溶性、良好的化学稳定性和生物相容性、低毒性和易于功能化等特点，近年来受到人们越来越多的关注。本文主要以木质纤维原料中所存在的糖类为碳源，从不同糖类碳源、制备方法、掺杂剂、量子产率和形成机理几个重要方面阐述糖类CQDs的合成情况，提出目前关于CQDs研究所存在的问题，并介绍了CQDs在化学探针、生物成像、传感器、光催化和发光二极管等领域的应用，以期为将来扩展糖类CQDs的用途提供一定的参考。

Abstract:Carbon quantum dots （CQDs）， as a new zero-dimensional fluorescent nanomaterial， has attracted more and more attention in recent years due to its advantages， such as excellent water-solubility， good chemical stability and biocompatibility， low toxicity and easy functionalization.This review mainly used carbohydrate present in lignocellulosic raw materials as carbon sources. The synthesis of carbohydrate CQDs was explained from several important aspects of different carbohydrate carbon sources， preparation methods， dopants， quantum yield and formation mechanism， and the current problems in the research of CQDs were raised， and the application of CQDs in chemical probes， biological imaging， sensors， photocatalysis and Light-emitting diode， etc， was introduced， which would provide some reference for the future expansion of the use of carbohydrate CQDs.
