Spectroscopic characterization of tin prepared by microwave technique

In this study, a microwave induced plasma jet (MIPJ) system was used to generate a non-thermal plasma jet with a standard frequency of 2.45 GHz in the microwave power range of 800 W at atmospheric pressure. Argon (Ar) gas was flowed around the burner in an adjustable ratio using a flow meter and controller. The effects of the microwave induced plasma jet (MIPJ) parameters, including applied voltage and Ar flow rate, on the macroscopic MP parameters were investigated. The parameters examined included plasma frequency ( \(\:{w}_{{p}_{e}}\) ), Debye length ( \(\:{\lambda\:}_{D}\) ), electron density ( \(\:{n}_{e}\) ), particle temperature ( \(\:{T}_{e}\) ), and number of particles ( \(\:{N}_{D}\) ). The spectral emission lines were analyzed and identified using the photometric method of emission spectroscopy. The results showed that the MPJ temperature decreased with increasing applied voltage, while an increase in the Ar-Ar gas flow ratio resulted in an increase in the Ar-Ar gas density, which led to an increase in the plasma frequency and Debye length. The nanoparticles were characterized using UV-Vis spectroscopy. The optical parameters of the samples showed a strong dependence on the average crystal size.
