The Department of Physics, College of Science, University of Baghdad, discussed the master’s thesis tagged “Spectroscopic diagnosis of copper, zinc and nickel plasma produced by jet plasma system” by student Tabarak Fadel Oraibi.
The research aimed to focus on generating DC plasma jets using different metals at different flow rates for argon gas, investigating plasma parameters using diagnostic techniques, especially photoemission spectroscopy, and obtaining the best optimal conditions for the elements Cu, Zn, and Ni to study plasma properties and apply them to solar cells.
The thesis arrived after mainly addressing the spectroscopy of plasma produced by zinc, copper, and nickel, using plasma jetting systems, along with investigating their spectral and morphological properties and their impact on plasma parameters that increase the spectral emission lines of plasma produced by copper, zinc and nickel metals with increasing argon gas flow, as plasma emission spectrum also revealed the presence of positive ionic types, including nitrogen radicals (N2), hydroxide (OH) and nitric oxide (NO). The inclusion of N2 in plasma jets increased the intensity of UV emission, which is attributed to an increase in the number of excited species enhancing spectral lines.
This symposium achieves one of the sustainable development goals represented by the seventh and fifteenth goals, which call for clean and affordable energy as well as life on earth.
