摘要
采用溶胶－凝胶工艺制备了用于汽车新型传感器的氧敏薄膜材料，包括过渡金属氧化物（ＭｏＯｘ、 ＴｉＯｘ、 ＣｒＯｘ）、钙钛矿型（ＳｒＴｉＯ３／ＬａＮｉＯ３、 ＬａＮｉＯ３、 ＬａＣｒＯ３）和类钙钛矿型（Ｌａ１－ｘＭｘＮｉＯ４）纳米粒子薄膜。结果表明，与传统氧传感器用的 ＺｒＯ２、 ＴｉＯ２半导体材料相比，这三类材料的阻温系数小，敏感度高。
Three types oxygen nanometer particle film materials, including transitional metal oxide (MoOx, TiOx and CrOx etc.), perovskite-type (SrTiO3/LaNiO3, LaNiO3 and LaCrO3 etc.) and perovskite-like type (La1-xMxNiO4), were prepared by sol-gel. The experimental results show that comparing with the traditional ZrO2, TiO2 semiconductor materials for oxygen sensor, these three types of materials have low coefficients of resistance-temperature, high sensitivity to the change of circumstance oxygen and rapid response.
