چکیده
|
Laser-induced breakdown spectroscopy (libs) data are characterized by a strong dependence on the acquisition time after the onset of the laser plasma. however,time-resolved broadband spectrometers are expensive and often not suitable for being used in portable libs instruments. in this paper we will show how the analysis of a series of libs spectra,taken at different delays after the laser pulse,allows the recovery of time-resolved spectral information. the comparison of such spectra is presented for the analysis of an aluminium alloy. the plasma parameters (electron temperature and number density) are evaluated,starting from the time-integrated and time-resolved spectra,respectively. the results are compared and discussed. © 2014 emanuela grifoni et al.
