Popis:	Room temperature responses of SnO 2 thin film sensors were investigated for ozone detection. The SnO 2 sensors were prepared using sol–gel process. Triton (X-100) surfactant was used as dispersant in the reaction system. The sensitive layers were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM) after heat treatments at 300 °C for 1 h. The effect of the dispersant on SnO 2 thin film sensor surface was found to lead to an enhanced response of about 3.5 times for the detection of ozone (500 ppb) at room temperature. Results are concordant for indicating the possibility of utilizing the sensor based on SnO 2 thin film for efficient detection of O 3 at room temperature without activation using catalysts or UV radiations.
