[en] A technology has been developed for the production of SnO2 + Nb2O5 (80 : 20 wt.%) semiconductor solid solution and the thin-film, nanoscaled resistive sensor based on it. The gas sensitivity characteristics of the sensor to different concentrations of liquefied petroleum gas (LPG) were investigated. The SnO2 sensor showed sensitive to this gas from temperatures up to 250°C in the presence of ultraviolet irradiation. The 250°C was chosen as the operating temperature and at this temperature the sensor showed sufficient sensitivity, high speed and repeatability of response over time. In the future the SnO2 structure can be used in security systems that detect LPG and measure its concentrations
