Abstract

An ArF laser-induced plasma spectroscopy (LIBS) study of lead ions in aqueous solutions was presented. Along a direction, transverse to the ArF beam, the luminous plume was imaged onto the entrance slit of a 0.5-m spectrograph equipped with 2400 lines/mm grating. Plume emissions were detected by a gateable intensified charge-coupled device (ICCD) mounted at the exit plane of the spectrograph. It was demonstrated that the LIBS analysis of Pb ions in water could be made sensitive if the plume created by an ArF laser pulse was reheated by a subsequent Nd:YAG laser pulse.
