| Abstract: | Nanocrystalline SnO2 films were successfully prepared by Sol-Gel method and were characterized. The impedance humidity characteristics of nanocrystalline SnO2 film are investigated; meanwhile, its humidity hysteresis is calculated. The experiments indicate that the humidity sensitivity becomes bigger and the humidity hysteresis becomes smaller, when the grain size decreases. |
