Multi-Technology Intelligent Detection of Explosives

Explosives detection has been a hot topic in international research in recent years. In order to improve the detection effect, this paper studies a portable intelligent detection method based on fluorescence and Raman detection technology. Silicon dioxide fluorescent porous films were prepared by doping graphene quantum dots, and nitroexplosives were detected sensitively by fluorescence quenching, and the trace detection effect was obtained. Explosives are detected in long distance, multi-environment and multi-mode by using Raman spectrum scattering effect, and the effect of portable, rapid and simultaneous detection is obtained. Combined with fluorescence-Raman dual detection technology, the information collected by detection is complementary and fused. Get more accurate and efficient information of the object to be detected, and use software to build an intelligent cloud detection database platform to intelligently detect different explosive molecules, so as to achieve the effect of rapid, sensitive, portable and real-time detection.
