The study used the optical emission spectroscopy method to present the effect of changing doping ratios and laser energy on plasma parameters. Plasma spectra were acquired across energy levels by zinc oxide combined with nickel oxide (ZnO_X: NiO_1-X) at x = 0.3, 0.5, and 0.7. The analysis of these airborne mixtures was carried out through the application of spectroscopy. The electron temperature results indicated that the range for x=0.3 was 0.446-0.491 eV, for x=0.5 was 0.470-0.486 eV, and for x=0.7 it was 0.474-0.489 eV. Differences in electron temperatures between compositions can lead to new technological applications and comprehension of physical phenomena. It was found that when the proportion of doping was increased, the intensities of the spectral lines, electron temperature (T_e), Debye number (N_D), and Debye length (λ_D) increased. In contrast, electron density (n_e) and plasma frequency (f_p) decreased with the increase of the laser energy; doped material's emission lines occurred more frequently in the mixed material. With these results, we obtain the best conditions for solar cell applications for zinc oxide elements combined with nickel oxide.
