【摘要】 以无机盐ＳｎＣｌ２·２Ｈ２Ｏ、（ＮＨ４）３Ｃｅ（ＮＯ３）６为原料，无水乙醇为溶剂，采用溶胶凝胶工艺制备了纯ＳｎＯ２及ＳｎＯ２∶Ｃｅ薄膜。研究了ＳｎＯ２∶Ｃｅ薄膜的热分解晶化过程和Ｃｅ掺杂对ＳｎＯ２薄膜电学及气敏性能的影响，发现ＳｎＯ２∶Ｃｅ薄膜在常温下对Ｈ２Ｓ气体具有较好的气敏性能，对ＳｎＯ２∶Ｃｅ薄膜的结构进行了表征更多还原

【Abstract】 Pure SnO 2 and SnO 2∶Ce thin films were prepared by the Sol Gel technique, using non alkoxide SnCl 2·2H 2O and (NH 4) 3Ce(NO 3) 6 as precursors, ethanol as solvent. The thermal decomposition and crystallization processes of SnO 2 and SnO 2∶Ce thin films and the effect of Ce dopant on the electrical and gas sensibility properties of SnO 2 thin films have been studied. We found that the SnO 2∶Ce thin film prepared by this method has very good as sensibility to H 2S at room temperature. The structural properties of SnO 2∶Ce thin film have been characterized更多还原
