“…The OES approach is widely used to diagnose plasmas in the laboratory and in nature to evaluate plasma properties such as the density of electrons, the temperature of electrons, material identification, and quantification of components in the plasma [17]. Because it requires no light source, optical emission spectroscopy is more readily suited for real-time control and monitoring than other optical diagnostics.…”

“…Excited levels are staffed in accordance with the distribution of Boltzmann and the states of ionization verify the Saha-Boltzmann equilibrium equation [19]. If the level populations are distributed in accordance with the Boltzmann equation, then the relative intensity of the emission line in the LTE plasma is given by [17]:…”

This study aims to analyze spectra in real-time for λ Draconids, σ Hydrids, μ Virginid, and one sporadic meteor using spectroscopic chemical analysis and diagnose plasma parameters. Good-resolution spectroscopy and a CCD camera for meteor observation were used concurrently to examine the ablation spectra of these meteorites in situ. The Boltzmann and Lorentz methods were then used to determine the temperature and density of electrons, the length of Debye, and the frequency of plasma. Furthermore, spectra data can be analyzed and compared to data from other sources. Spectrum tests can be utilized to identify the chemical structure of meteorites' plasma.

“…In addition to laser properties such as wavelength, pulse energy, and pulse width; the nature of the target material and the surrounding environment; as well as the measuring equipment, are factors that can impact LIBS [6][7] . As a result of these factors, the repeatability of the LIBS signal is low, which is one of the key challenges that hamper the deployment of LIBS technology 8,9 . The study of hardware improvement, as well as research into the system through experiment equipment, measurement environment, optimizing target material properties, and other methods of improving the accuracy of experimental data have been conducted to overcome matrix effects and improve the accuracy of experimental data 10 .…”

Optical Emission Spectrometry technique (OES) is used to analyze the plasma generated from a (Ni) target illuminated with a Q- Switched (Nd:YAG) laser at various energies in the air. Boltzmann-Plot and Stark broadening methods were used to calculate the plasma parameters including electron density (ne), electron temperature (Te), plasma frequency (fp), and Debye length (λD). It is shown that the values of (ne), (Te), (λD) and (fp) increase with increasing laser energy with the calculated electron temperature values ranging between 0.934 - 1.479 eV.

In this study, the surface of the epoxy/Al composite is treated using a dielectric barrier discharge (DBD) plasma in the presence of air. The epoxy composite was prepared by mixing 0.1g and 0.3 g aluminum powder with epoxy resin and its hardener in a ratio of 3:1. The surface epoxy/Al composite as a dielectric barrier layer (DB) is studied at an applied frequency of 8 kHz and at three exposure times 0, 2, and 4 min. The UV degradation process has been studied using UV-Visible spectroscopy, for these polymers. The absorbance intensity in the UV region (200–320 nm) was high. The absorbance level decreased after 2 minutes and increased after 4 min exposure time. Before exposure to plasma, the epoxy/Al composite at 0.1 g Al had an optical band gap of 3.72eV, while it was 3.6 and 3.42 eV after 2, and 4 min exposure time, respectively. For the composite with 0.3 g Al, the optical band gap was 3.6 eV before exposure which decreased to 3.2 and 2.78 eV after exposure to plasma for 2 and 4 min, respectively. This was due to the increase in conductivity for epoxy/Al composite with 0.3 g Al. Also, after treatment, physical changes happened on their surfaces as well as chemical changes which have been test using AFM technique. Three spectra are characterized by the appearance of halos extending in 2θ range from 16˚ to 45˚ for the XRD spectra of the untreated and treated Epoxy/Al composite samples at several exposed time (0, 2, and 4 min).
