Abstract
Zinc oxide (ZnO) thin-films were grown on glass substrates by using simple wet chemical approach and then the films were annealed at 450 °C in air atmosphere for 2 h. The scanning electron microscopy images could confirm the uniform deposition and formation of cabbage leaf-like ZnO nanostructures. The optical band gap was found to be 3.14 eV for annealed films. The sensor showed higher sensitivity towards liquid petroleum gas (LPG) at optimized temperature of 200 °C. The response and recovery times with 200 ppm of LPG were found to be ∼6 and ∼ 8 s, respectively.
