摘　　要：以 L a(NO3) 3· 6 H2 O和 Ni(NO3) 2 · 6 H2 O为原料 ,采用柠檬酸为螯合剂 ,利用溶胶 -凝胶法合成了钙钛矿型稀土复合氧化物 L a Ni O3纳米陶瓷薄膜 。LaNiO 3 thin film on the Al 2O 3 substrate was prepared by the sol-gel method,in which La(NO 3) 3·6H 2O and Ni(NO 3) 2·6H 2O were used as raw materials,citric acid was used as chelating agent.the oxygen sensitivity of the film is discussed mainly.The effects of sintering temperature and doping of Pt and Ce on the oxygen sensitivity are also studied.
