It was found that the treatment of samples with oxygen plasma for 5 min led to a decrease in transparency by 1.11 and 1.17 times. On the transmission spectra, a decrease in the transmittance at a wavelength of 450 nm to 38.1% (1.24 times) in samples obtained from solutions with the addition of NH<sub>4</sub>F and up to 29.9% (1.53 times) in samples obtained from solutions with the addition of NH<sub>4</sub>OH is observed. The formation of tin oxide (II) under the influence of the reducing properties of hydrogen plasma is assumed. At the same time, the formation of metal tin from tin dioxide is not observed here. Due to the decreasing of transmission coefficient in the long-wave region of the spectrum. There is an increase in surface resistance after treatment with oxygen plasma, due to filling oxygen vacancies. Treatment of hydrogen plasma films leads to a decrease in surface resistance. Perhaps due to the increase in oxygen vacancies under the influence of hydrogen plasma. Within five minutes, the oxygen and hydrogen plasma had a more active effect on the films obtained from the solution with the addition of ammonium hydroxide, which is associated with a higher porosity of the sample. Consequently, irrespective of the time of plasma exposure with increasing the surface of contact between ionized gases and the film material, the interaction efficiency will increase.</p>}, number={1}, journal={Eurasian Chemico-Technological Journal}, author={Mukhamedshina, D.M. and Fedosimova, A.I. and Dmitriyeva, E.A. and Lebedev, I.A. and Grushevskaya, E.A. and Ibraimova, S.A. and Mit’, K.A. and Serikkanov, A.S.}, year={2019}, month={Feb.}, pages={57–61} }
