2,4,6-Trinitrotoluene
(TNT), a leading example of nitroaromatic explosives, is causing wide concern. In this study, SERS spectra
of TNT solution in silver colloids have been successfully measured and a comparison was drawn with the
normal Raman spectra of bulk TNT. The silver colloids were prepared by the microwave heating method
and characterized by UV–Vis spectra and the scanning electron microscopy (SEM).
