Abstract

Time-resolved emission spectroscopy was employed to detect excited species formed in the laser ablation of superconductor Pb-Bi-Sr-Ca-Cu-O by an excimer laser at various background gas pressures.

A simple model has been created to explain the chemical kinetics of reactions in a plasma plume by its expansion. We explained the time dependence of plasma emission on the wavelengths of lead, strontium and their oxides. For the purpose of this paper, we determined reaction rates of lead deexcitation and the rate of recombination of Pb+ ion.
