摘　　要：潜手印的显现是公安人员侦破案件的关键,也是证明犯罪的有效依据。稀土铕配合物很大程度解决传统粉末法显现潜在手印所面临的对比度低、选择性差,易受背景颜色干扰等难题,为潜在手印显现提供新的研究思路。本文旨在对近年铕配合物的敏化发光机理、铕配合物的合成方法及其在法庭科学领域的应用研究进展等方面进行综述,分析铕配合物的研究对刑事科学技术发展的重要意义,结合铕配合物在手印显现的应用中有待进一步研究和提升的方面,如提高铕配合物的热稳定性、在水溶液及潮湿环境中维持其稳定性及荧光效率,提出未来研究展望。The appearance of potential fingerprints is the key for public security personnel to solve cases and is also an effective basis for proving crimes.Rare earth europium complexes have greatly improved the problems of low contrast,poor selectivity and easy to be interfered by background color in the traditional powder method for the development of potential fingerprints,and provided a new research idea for the development of potential fingerprints.In this paper,the sensitization and luminescence mechanism of europium complexes,the synthesis methods of europium complexes and their application in forensic science are reviewed.The important significance of the research of europium complexes for the development of criminal science and technology and the aspects to be further studied and improved in the application of europium complexes in fingerprint display are analyzed,that is,improving the thermal stability of europium complexes,maintaining its stability and fluorescence efficiency in aqueous solution and humid environment.
