摘要：
Sr-doped SnO2 thick film gas sensors were prepared for domestic liquefied petroleum gas (LPG) determination down to several ppm levels using the screen-printing technique. Characterization of Sr-doped SnO2 thick film was investigated by XRD, XPS and DTA-TGA analyses. The sensitivity, selectivity, sintering temperature, and static and dynamic measurement were investigated. The results showed that the Sr-doped SnO2 thick film sensor is suitable for several ppm levels LPG determination because of the high sensitivity (S = 12.7 to 10 ppm LPG). The dynamic measurements showed that the sensor exhibited high sensitivity and selectivity to domestic LPG at 210-300 degrees C.
