摘要：

Aluminum–Zinc co-doped SnO2 thin films were successfully synthesised onto glass substrates by spray-pyrolysis processing. The structural, morphological, optical and electrical properties of co-doped thin films as deposited at 400˚C, 500˚C, and 600˚C and were studied using various techniques. The XRD results show the films possessed polycrystalline SnO2 with tetragonal rutile structure. The average crystallite size found to be 39 (pure) and 31 nm (co-doped). AFM images showed the annealing temperature effects surface morphology of the films. The transmittance of thin films is up to 80 to 85% in the visible region. The bandgap of the films has been calculated for different annealing temperature and they lie within the range of 3.87–4.21 eV. Electrical properties of co-doped thin films were studied through Hall measurement. Furthermore, the prepared co-doped thin films will be useful in optoelectronics and gas sensing applications. © 2019, © 2019 Informa UK Limited, trading as Taylor & Francis Group.
