The sensing and dierentiation of explosive molecules is the key for security. By combining the fluorescence lifetimes and wave length, faster results can be obtained from smaller amounts of sample. Here, three explosives (2, 4, 6-trinitrotoluene (TNT), cyclotrimethylene- trinitramine (RDX), and ammonium nitrate (NH4 (NO) 3). Are excited using pulsed uv laser, The sharp fluorescence emissions of that materials, can give us a complete information that make them ideal for such a system. Pattern analysis of the uorescence spectrum data allows for standoff explosive detection and identication with limits-of-detection in the (ppb) range, providing a number of advantages, including the reduction of the effects due to photo bleaching, catering, and intensity variations in the excitation source.
