To fabricate more excellent NO 2 sensor with high sensor response and good linearity between the sensor response and NO 2 concentration, the microstructure of WO 3 lamellae was controlled by adding nano-particles of SnO 2. It was found that the sintering of WO 3 lamellae was inhibited by adding nano-particles of SnO 2. The device using WO 3 lamellae added a small amount of SnO 2 nano-particles had the highest sensor response, exhibiting a high sensor response (S = 60-540) even to dilute NO 2 (100-1000 ppb) in air at 200°C.
