چکیده
|
Laser-induced breakdown spectroscopy (libs) is a new approach for determination and characterization of various nanomaterials structures. in this work, libs emission spectra of different species of nanocarbon nanomaterials (carbon allotropes) were described. ablation was performed using an nd: yag laser at 1064 nm in ambient air at atmospheric pressure. results are consistent with the atomic emission lines of carbon or molecular bands, c2 being released directly from the target, and cn being formed later by the interaction of c2 with nitrogen gas (n2) in the atmospheric ambient of plasma. it was indicated that probably there is a relationship between c2 emission from the plasma and the presence of aromatic rings (containing carbon-carbon double bonds) in the compounds
