Измерения проводились во время осаждения покрытия из нитрида ниобия (NbN) методом магнетронного распыления при поддержке расстояния между зазорами 0,06 м и общей скорости потока 40 cтандартных кубических сантиметров в минуту. Температура электронов оценивалась путем построения графика Больцмана с несколькими ионными линиями Ar+, а плотность электронов определялась из отношения интенсивностей атомных и ионных линий с использованием уравнения Саха–Больцмана. Результаты исследований показали, что увеличение приложенного напряжения приводит к повышению температуры электронов, в то время как увеличение рабочего давления приводит к снижению температуры электронов. Наоборот, плотность электронов уменьшается с увеличением приложенного напряжения и увеличивается с ростом рабочего давления. Показано, что введение небольшого количества N2 в источник разряда во время процесса осаждения NbN приводит к улучшению электрических характеристик плазмы тлеющего разряда.</p></abstract><trans-abstract xml:lang="en"><p>   The combination of optical emission spectroscopy with models of plasma light emission represents a non-intrusive and adaptable approach for determining plasma characteristics.</p><p>   This study aimed to investigate the plasma electron temperature, electron density, and other parameters of plasma within context DC magnetron sputtering, under a various experimental condition, in the existence of a Niobium target and an Argon:Nitrogen gas mixture.</p><p>   To evaluate electron temperature and electron density, optical emission spectroscopy was employed at a range of discharge voltages (400–800 V) and gas pressures (0.04–3.3 mbar). The measurements were taken during the deposition of a Niobium nitride coating with in magnetron sputtering setup, maintaining a gap distance of 0.06 m and a total flow rate of 40 Standard Cubic Centimeters per Minute. The temperature of electron was assessed using Boltzmann plot strategy with several ion lines Ar+ lines, while density of electron was determined from the intensity ratio of atomic to ionic lines using Saha-Boltzmann equation. The results demonstrate that, for the plasma under investigation, an increase in the applied voltage lead to an elevation of temperature of electron, while an increase in the working pressure results in a reduction in the temperature of electron. Conversely, the density of electron decreases with the increasing applied voltage and increases with rising working pressure. Additionally, the findings indicate that the introduction of a modest quantity of nitrogen gas into the discharge source resulted in improved electrical characterization of the glowing discharge plasma during the Niobium nitride coating deposition process.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>оптическая эмиссионная спектроскопия</kwd><kwd>параметры плазмы</kwd><kwd>тлеющие разряды</kwd><kwd>электронная температура</kwd><kwd>электронная плотность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>optical emission spectroscopy</kwd><kwd>parameters of plasma</kwd><kwd>glow discharges</kwd><kwd>electron temperature</kwd><kwd>electron density</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Авторы выражают благодарность и признательность лабораториям Багдадского университета и Министерству науки и технологий Республики Ирак за выполнение требований данного исследования</funding-statement><funding-statement xml:lang="en">Our thanks and appreciation to the laboratories of the University of Baghdad and the Ministry of Science and Technology for completing the requirements of this study</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Laroussi M.
