Zinc tin oxide (ZTO) is investigated as a photoluminescent sensor for oxygen (O); chemisorbed oxygen quenches the luminescence intensity. At the same time, ZTO is also studied as a resistive sensor; being an n-type semiconductor, its electrical conductance decreases by adsorption of oxygen. Both phenomena can be exploited for quantitative O sensing. The respective sensor responses can be described by the same modified Stern-Volmer model that distinguishes between accessible and non-accessible luminescence centers or charge carriers, respectively. The impact of the temperature is studied in the range from room temperature up to 150 °C.
氧化锌锡（ZTO）被研究用作氧气（O）的光致发光传感器；化学吸附的氧气会猝灭发光强度。同时，ZTO也被作为电阻式传感器进行研究；作为一种n型半导体，其电导率会因氧气吸附而降低。这两种现象都可用于定量氧气传感。各自的传感器响应可以用相同的修正斯特恩-沃尔默模型来描述，该模型分别区分了可及和不可及的发光中心或电荷载流子。研究了温度在室温至150°C范围内的影响。
