Abstract :In this study, UV-VIS-NIR insert ignore into journalissuearticles values(Ultraviolet Visible Near-Infrared); spectra emitted from Argon Glow discharge plasma in a low vacuum were recorded with a high-resolution Czerny-Turner type spectrometer. Argon plasma was produced at a pressure of 5mTorr and with a voltage of 584 V. Argon plasma was produced between two parallel stainless steel plates anode and cathode with a diameter of 15 cm, a thickness of 0.8 cm, and a distance of 13 cm between them. The radiative and collisional processes of the Argon plasma medium were modeled by the PrismSPECT atomic physics software insert ignore into journalissuearticles values(Software);. The distributions of ion densities were calculated using the Saha-Boltzmann equation. The intensity of the excited energy levels of Arinsert ignore into journalissuearticles values(I); and Ar insert ignore into journalissuearticles values(II); ions were calculated in the electron temperature range of insert ignore into journalissuearticles values(0.4-3.5eV); and the mass density of insert ignore into journalissuearticles values(10-4-10-1gr/cm3);. The UV-Visible-NIR spectra were simulated and compared with experimental spectra. The ratios of the intensities of the ArII/ArI insert ignore into journalissuearticles values(1s22s22p63s23p44f1/1s22s22p63s23p54p1); spectral lines were obtained for different plasma temperatures and densities. The temperature of the argon plasma was obtained from the spectral line intensity ratios.
