We examined room temperature gas sensing potential in Ceria (CeO₂) doped nanocrystalline SnO₂ clad modified fiber optic gas sensor. Prior to the investigation, the samples were characterized via SEM/EDS and HRTEM for their morphology and detection of any external contamination. The spectral response of the fiber optic gas sensor was recorded for various concentrations (0–1000 ppm) of toxic gases (Benzene, Methanol, Chloroform and Ammonia). The sensor exhibited noble response towards benzene, and the results are discussed in detail.

在包层改性氧化铈掺杂氧化锡光纤有毒气体传感器应用中的高灵敏响应

我们研究了在二氧化铈 (CeO ₂ ) 掺杂的纳米晶 SnO ₂包覆改性光纤气体传感器中的室温气体传感电位。在调查之前，通过 SEM/EDS 和 HRTEM 表征样品的形态和检测任何外部污染。光纤气体传感器的光谱响应记录了各种浓度（0-1000 ppm）的有毒气体（苯、甲醇、氯仿和氨）。该传感器对苯表现出良好的响应，并详细讨论了结果。
