摘要
采用非醇盐溶胶－凝胶工艺制得纳米微晶ＳｎＯ２多孔薄膜，该法易于实现ＳｎＯ２与多种添加剂的均匀掺杂。通过调整薄膜的微观结构使薄膜对Ｃ２Ｈ５ＯＨ和ＣＯ在最佳工作温度的灵敏度比调整前分别提高了３倍和１４倍。
A unalcolate SolGel method was employed to prepare nanocrystalline SnO2 porous thin film.By this method SnO2 thin film could be easily doped with various additive.The microstructure of the film was adjusted and the gas sensing properties were improved greatly.
