Abstract
AbstractIn the present work, the authors have successfully deposited uniformly upright standing ZnO nanorods on glass substrates by using simple one‐pot chemical bath deposition method. XRD reveals the polycrystalline nature of ZnO thin films. SEM micrograph depicts the well resolved standing growth of ZnO nanorods on glass substrate with an average diameter of 200–300 nm. The optical measurements show that the band gap is 3.3 eV. The detail investigation of LPG sensing study demonstrates the lower operating temperature 190°C with gas response of 105%, with fast response/recovery times 80/70 s, respectively. In addition, the LPG gas uptake capacity remained sensible up to 10 000 ppm.
