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

Abstract EN

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.
