LPG Gas Sensing Performance of Nanostructured CdSnO3 Thin Films

Nanostructured CdSnO3 thin films were prepared by spray pyrolysis technique. The nanostructured CdSnO3 film showed selectivity for LPG gas over other conventional gases. The maximum LPG response of 1460 for the sample S2 at 350 °C was achieved. The quick response (TResponse = 5 s) and fast recovery (Tsub>Recovery = 11 s) are the main features of this film. Additionally, the stability of the prepared sensor has been studied. As prepared thin films were studied using XRD, FE-SEM, and EDAX to know crystal structure, surface morphology, and elemental composition, respectively. The results are discussed and interpreted.
