Synthesis of Fluorescent Probes for Ga/Eu3+/DPA Nano Rare Earth Coordination Compounds and Quantitative Detection of Cu2+ in Gun Shot Residues

Gun Shot residues (GSR) are important physical evidence because of their potential, wide distribution and difficulty in destruction. To overcome the disadvantages traditional detection methods, such as time-consuming, relying on large instruments weak intuition, Ga/Eu3+/DPA rare earth complex probes were synthesized for quantitative Cu2+ shooting by hydrothermal method. The morphological size, molecular structure fluorescence properties characterized transmission electron microscopy, infrared spectroscopy spectroscopy. Then, synthesis conditions optimized, anti-ion interference capability was investigated. After that, linear relationship between intensity concentration Finally, according to residue distance bullet holes detected ICP-MS, experiment verified that fluorescent probe is fully capable residue, expected play an role application criminal technology.
