AbstractThin film of lanthanum nickelate (LaNiO3) has been prepared by the sol-gel process based on the amorphous citrate precursors. The sheet resistance of LaNiO3 thin film greatly decreases and trends towards a stable value with increasing the repeated dipping-calcining cycles. The sheet resistance of about 1.2 mu m thick LaNiO3 thin film produced by the dipping-calcining 10 cycles is about 22.4 Omega at room temperature and less sensitive to temperature in the P-O2 range from 10(3.3) to 10(5) Pa or in the lean-burn region (lambda = 1.15). The sensitivity and response characteristics of the LaNiO3 thin film sensor have been investigated in the exhaust gas of air-propane combustion. It has been shown that thin film sensor has high sensitivity, fairly good response and reproducibility from h = 1.15 to 0.85 and vice versa, and no temperature compensation is needed for stoichiometric air/fuel control over a 300-800 degrees C range. The thin film sensor is a promising A/F sensitive sensor that needs no temperature compensation. (C) 2000 Elsevier Science S.A.
