摘　　要：文章尝试利用多种方法制备纳米银与发光材料的淬灭体系,择优与8-羟基喹啉铝配合得到了纳米银-8-羟基喹啉铝淬灭体系。即使没有硝酸、双氧水等强氧化性物质的存在,汗潜指纹中含有的氯离子仍然可以破坏淬灭体系,在有指纹的地方再现较强荧光,从而显现出指纹。该体系试用于指纹显现,已在镀锌板、陶瓷等材质上取得了良好效果。The study introduces a new method to detect latent fingerprints based on the quenching system. We tried to use various methods to prepare quenching system, using nanosliver and luminescent materials. Finally, we selected the best of these, the quenching system of sliver Nanoparticles-8-Hydroxyquinoline aluminum salt（Alq3）, which can still be destructed even without nitric acid, hydrogen peroxide present, because of fingerprints containing chloride ions. The presence of a fingerprint may reemerge stronger fluorescence, thus showing fingerprints. The quenching system is applied to detect or locate fingerprints, which has been achieved good effects on galvanized sheet, ceramic and other materials.
