摘要
潜在指纹的提取和显现一直是潜在指纹学领域研究热点之一,长余辉显现材料在手印显现领域具有自己独特的优势,它有效解决了传统粉末显现法存在的复杂背景颜色干扰以及对比度低等问题。本文介绍了长余辉材料的发光机理和制备方法,并简述了长余辉显现材料在法庭科学潜在手印显现领域的应用。旨在总结近年来长余辉手印显现材料的制备和显现效果,为该领域未来研究方向提出展望。
The extraction and development of latent fingerprints has always been one of the research hotspots in the field of latent fingerprinting.Long afterglow developing materials have their own unique advantages in the field of fingerprinting,which effectively solves the problems of complex background color interference and low contrast existing in traditional powder developing methods.In this paper,the luminescence mechanism and preparation method of long afterglow materials are introduced,and the application of long afterglow materials in the field of potential handprint development in forensic science is briefly described.The aim of this paper is to summarize the preparation and effect of long afterglow handprint developing materials in recent years,and put forward the prospect of future research direction in this field.
