利用镧系发光显现纸张上的潜在指纹

Showed Latent Fingerprint in Paper by Lanthanide Luminous

简要介绍镧系发光的基本性质 ,着重阐述利用镧系化合物染色潜在指纹 ,使其发出较强荧光 ,然后用照相的方法记录荧光信息 ,显现肉眼看不清的指纹细节。也详细叙述了实验环节和结果 ,并对实验结果进行了系统分析。

This paper introduces basic nature of lanthanide luminous concisely and expounds the dye of latent fingerprint using lanthanide compounds so that fingerprint engenders stronger fluorescence and then records fluorescence information and shows invisible fingerprint details.The experimental procedure and result were stated in detail and analysed systematically.
