以LiNO 3掺杂的（Gd0.9La0.1）2 O3为传感辅助电极，将三价铝阳离子导电（Al0.2Zr0.8）20/19 Nb（PO 4）3和二价氧阴离子导电氧化钇稳定氧化锆（YSZ）复合，制备了一种新型的中温固体电解质型NO气体传感器。本传感器显示出快速、稳定、连续和可重复的响应的实际性能，低至523 K，并且在传感器电动势输出和NO浓度的对数之间清楚地观察到遵循能斯特理论关系的线性关系。由于采用LiNO 3掺杂的（Gd0.9La0.1）2 O3辅助电极的本传感器显示出如此高的传感性能，因此它有望成为一种适用于523 K左右中温范围的新型NO气体传感器件。
A new solid electrolyte type nitrogen monoxide (NO) gas sensor which can operate in the intermediate temperature region was fabricated by the combination of trivalent aluminum cation conducting (Al0.2Zr0.8)20/19Nb(PO4)3and divalent oxide anion conducting yttria stabilized zirconia (YSZ) with LiNO3-doped (Gd0.9La0.1)2O3as the sensing auxiliary electrode. The present sensor shows such a practical performance of a rapid, stable, continuous, and reproducible response as low as at 523K, and the linear relationship, which obeys the Nernst theoretical relationship, was clearly observed between the sensor EMF output and the logarithm of the NO concentration. Since the present sensor using the LiNO3-doped (Gd0.9La0.1)2O3auxiliary electrode shows such a high sensing performance, it is greatly expected to be a new type of the NO gas sensing device applicable in the intermediate temperature range of around 523K.
