Structural, Morphological, Optical and Hydrogen Gas Sensing Properties of ZnO Thin Film

Hansraj Sharma, Jagavendra Yadav, Subodh Srivastava, Mangej Singh

Abstract: The objective of this study is to improve the hydrogen gas detection capabilities of thin films of zinc oxide (ZnO). The sol - gel method was employed to synthesis ZnO thin films, which were then manufactured using the spin coating technique. These films were subsequently analyzed using X - ray diffraction (XRD), Scanning electron microscopy (SEM), AFM, and UV - Vis spectroscopy to assess their structural, morphological, and optical features. The gas sensing performance was assessed by subjecting the films to varied quantities of hydrogen gas. ?The gas sensing behavior was identified by observing the resistance change following exposure to hydrogen gas, using computer - controlled, domestically built hydrogen gas sensing equipment.

Keywords: ZnO, XRD, SEM, AFM, and hydrogen gas sensor
