Abstract
In this research, optical emission spectroscopy measurement technique OES was used to determine and calculate the electron density parameter of the low pressure cold glow discharge Ar plasma. For achieve this purpose, the Stark broadening of Balmer line of hydrogen spectrum Hβ obtained from plasma system in different pressure conditions were used to calculate the electron density. By calculating the electron density values obtained at different plasma pressures of 0.05, 0.13, and 0.65 Torr, it was found that there is a significant relationship between the plasma pressure and its electron density. The results showed that with the increase in the plasma pressure, its electron density also increases. Therefore, for use of this plasma system in different applications such as in industrial applications, treatment of biomaterials, medicine or print and packaging of polymers, by changing the pressure parameter of plasma system, the optimum conditions of surface plasma treatment can be obtained plasma system, the optimum conditions of surface plasma treatment can be obtained.
