Abstract
Spectroscopy is a field of study that observes the interactions of light, or electromagnetic radiation, with a system and identifies properties of materials based on these interactions. Laser-induced breakdown spectroscopy (LIBS) has been used extensively in the UV-visible region of the electromagnetic spectrum, but not in the infrared region. Infrared emission spectroscopy (IRES) combines the advantages of material dependent structural information of traditional infrared spectroscopy with the “zero-background” nature of UV-fluorescence detection. This study shows that these infrared emissions are observable when used in tandem with LIBS excitation techniques. With improvements in spectroscopic equipment for identification, IRES techniques could be used to identify contaminations in food or drugs or explosive material residues in public spaces with improvements in spectroscopic equipment for identification
