Application of Long Afterglow Materials in the Field of Fingerprint Developing
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 prospectof future research direction in this field.
