Study of parameters of cadmium sulfide plasma produced by LIBS technique by using optical emission spectroscopy


The current study was carried out to reveal the plasma parameters electron temperature (T_e), electron density (ne), plasma frequency (fp), Debye length (〖 λ〗_D) and Debye number (N_D) for CdS using the laser induced breakdown spectroscopy LIBS for the purpose of analyzing and determining spectral emission lines. The valuable of electron temperature for CdS in the range (0.746-0.856) eV and the electron density (3.909-4.691)×1018 cm-3. Finally, plasma parameters of CdS were discussed through nano second laser that generated plasma using different laser energy (500-1000) mJ.
