Abstract

Nanocrystalline cadmium indium oxide (CdIn2O4) thin films of different thicknesses were deposited by chemical spray pyrolysis technique and utilized as a liquefied petroleum gas (LPG) sensors. These CdIn2O4 films were characterized for their structural and morphological properties by means of X-ray diffraction (XRD) and scanning electron microscope (SEM), respectively. The dependence of the LPG response on the operating temperature, LPG concentration and CdIn2O4 film thickness were investigated. The results showed that the phase structure and the LPG sensing properties changes with the different thicknesses. The maximum LPG response of 46% at the operation temperature of 673 K was achieved for the CdIn2O4 film of thickness of 695 nm. The CdIn 2O4 thin films exhibited good response and rapid response/recovery characteristics to LPG.
