摘要：

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. (C) 2021 Published by Elsevier B.V.
