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.
