Nano-crystalline porous tin oxide thin film was successfully prepared by a sol-gel technique and evaluated for CO sensing. The surface morphology, electrical conductance and CO sensitivity of the tin oxide thin films calcined at various temperatures (500–800°C) were studied and compared. The particles were in the diameter range of 7–15 nm and the pore diameters were about 1.6–9 nm. The tin oxide film calcined at 700°C deposited onto interdigitated electrodes showed high CO sensitivity with relatively fast response (∼ 4 min) and recovery time (∼ 1 min), respectively. The results indicate the advantages of using nano-crystalline porous materials for thin film sensor development. |
