• 論文の詳細を見る

• The effects of a water treatment of the LaF_3 single crystal on an LaF_3-based oxygen sensor were investigated. It was found that the oxygen-sensing properties were significantly affected by the water treatment depending on the perovskite-type oxides (LaCrO_3, LaCoO_3, La_<0.8>Ca_<0.2>MnO_3) used as the sensing electrode material and the duration of the treatment. As revealed by XPS, the treatment induced the incorporation of oxygen in the surface region of the LaF_3 crystal, leading to an increase in the number of electrons of the electrochemical reduction of oxygen from 1 or 2 to 4.
