Laser-induced breakdown spectroscopy characterization of Al in different matrix

Abstract

Some experimental investigations were carried out with the samples of metal Al and AlCl₃ solutions. It is found that the spectrum varies with the change of experimental setup parameters both in Al bulk material and AlCl₃ solutions. The temporal evolution properties and the affection of incident laser energy on the laser-induced breakdown spectroscopy (LIBS) signals were also discussed. The lifetime of laser induced plasma in AlCl₃ solutions is found to be about 30 ns which is much shorter than in solid materials. Compared with the solid samples, the Al LIBS signals in AlCl₃ solutions require higher laser energy. Under the optimized conditions, the detection limit of Al in AlCl₃ solution was determined to be around 1000 ppm for the system we used.
