摘　　要：本文是以溶剂热法合成铕金属有机框架化合物的实验为基础,实验将铕改成与其同一周期的金属钆和镨,分别将两者合成的化合物烘干、研磨,然后使用扫描电镜对合成的化合物SEM表征,再使用其对指纹进行刷显并且与传统荧光粉末进行比对。实验结果表明:合成的金属钆有机框架化合物呈黄褐色,且能够较好的显现指纹;金属镨有机框架化合物成淡绿色,且难以研磨成近似粉末状,所以无法使用其来刷显指纹。This article is based on solvent hot method synthesized compounds based on the experiment of europium metal organic framework,the experiment will europium metal gadolinium and praseodymium change rather than the same period,respectively,the two synthetic compounds,drying,grinding,and then we used the scanning electron microscopy,SEM characterization of the synthesized compounds were to use the brush on the fingerprint shows and compares with the traditional fluorescent powder.The results show that the synthesized organic framework compound of gd is yellow-brown in color and can show fingerprint well.Praseodymium,on the other hand,is pale green and hard to grind into a near-powder,so it cannot be used for fingerprints.
