摘　　要：碳量子点(CQDs)距今已被提出多年,由于碳量子点自身物理和化学性质十分突出,引起国内外的广泛研究。随着人们对其研究的深入,碳量子点的性质和原理也不断被人们了解,并逐渐开始掌握其制备与应用。综述了3种碳量子点制备方法的国内外研究进展,分别是化学氧化法、微波辅助法和水热法,详细阐述了碳量子点的表面修饰以及碳量子点在爆炸物检测方面的应用,最后对碳量子点在爆炸物检测方面存在的问题进行分析和展望。Carbon quantum dots(CQDs)have been proposed for many years.Due to their outstanding physical and chemical properties,carbon quantum dots have been extensively studied at home and abroad.With the in-depth study of carbon quantum dots,the properties and principles of carbon quantum dots are gradually understood,and gradually began to master their preparation and application.In this paper,the research progress of three carbon quantum dots preparation methods at home and abroad was reviewed,which were chemical oxidation method,microwave assisted method and hydrothermal method.The surface modification of carbon quantum dots and the application of carbon quantum dots in the detection of explosives were described in detail.Finally,the existing problems of carbon quantum dots in the detection of explosives are analyzed and prospected.
