采用物理气相沉积法在未加热的衬底上制备了氧化锡和氧化铈混合氧化物薄膜。将膜在空气中在500 °C下退火两小时，并使用X射线光电子能谱、原子力显微镜和光学分光光度法进行表征。X射线光电子能谱和原子力显微镜的结果表明，薄膜是高度多孔的，我们的薄膜的孔隙率被认为是在11.6- 21.7%的范围内。研究了该膜对一氧化碳的检测，发现其具有高度的灵敏度。我们发现，430 °C是检测浓度低至5 ppm的CO气体的最佳工作温度。我们的传感器表现出快速的响应和恢复时间分别为26秒和30秒。
Thin films of tin oxide mixed cerium oxide were grown on unheated substrates by physical vapor deposition. The films were annealed in air at 500 °C for two hours, and were characterized using X-ray photoelectron spectroscopy, atomic force microscopy and optical spectrophotometry. X-ray photoelectron spectroscopy and atomic force microscopy results reveal that the films were highly porous and porosity of our films was found to be in the range of 11.6–21.7%. The films were investigated for the detection of carbon monoxide, and were found to be highly sensitive. We found that 430 °C was the optimum operating temperature for sensing CO gas at concentrations as low as 5 ppm. Our sensors exhibited fast response and recovery times of 26 s and 30 s, respectively.
