Sensing Signatures Mediated by Chemical Structure of Molecular Solids in Laser-Induced Plasmas

Abstract: Laser ablation of organic compounds has been investigated for almost 30 years now, either in the framework of pulse laser deposition for the assembling of new materials or in the context of chemical sensing. Various monitoring techniques such as atomic and molecular fluorescence, time-of-flight mass spectrometry, and optical emission spectroscopy have been used for plasma diagnostics in an attempt to understand the spectral signature and potential origin of gas-phase ions and fragments from organic plasmas.

“…In a pure nitrogen atmosphere, less than 10% of the nitrogen in CN molecules originates from the sample itself but, rather, comes from the ambient gas. Despite the 15 N-to-C ratio of 1:2 in urea, 14 N of the ambient gas appears to be the preferential source for CN. This indicates a strong interaction of the ablated material with the ambient nitrogen.…”

“…Moreover, it is capable to simultaneously provide elemental as well as molecular spectroscopic information, which is especially interesting for the analysis of organic materials such as plastics. Indeed, as an eminent elemental analysis technique, LIBS has been also demonstrated to be suitable to reveal molecular structure of organic materials [13][14][15]. The combination of elemental and molecular emissions, especially those of C 2 and CN radicals, offers an ensemble of spectral features to characterize plastics and organic materials in general [16][17][18][19][20][21][22].…”

“…Plasma modeling is a diverse subject [9,10] with variety of applications. Recently, much attention has been paid to formation and detection of molecules in LIPs of organic [11,12] and inorganic [13,14] origins. Molecular reactions occur at sufficiently low temperatures at which anions may form.…”
