Abstract
Nanocrystalline tin oxide films were obtained on glass and metal substrates by immersing into the solution of tin carboxylate, centrifuging of the substrate with the solution, followed by thermal treatment. A distinguishing feature of the proposed method is the use of extraction for the synthesis of precursors, which allows us to obtain the precursor material free from any impurities. It was established that the sensitivity of tin oxide films to the gases depends on pyrolysis temperature and is maximal for the films pyrolyzed at 400 oC.
