Abstract

The two-step SILAR approach was used to create pure and Aluminium (Al) doped Zinc Oxide (ZnO) thin films. The
structural, optical, and morphological properties of pure ZnO thin film and ZnO thin films doped with Al (1, 3, and
5)% were investigated. All the sample’s diffraction peaks were mapped to a hexagonal Wurtzite form. For the
synthesized thin films, dislocation density, crystallite size, microstrain, and lattice parameters were calculated. Pure
ZnO thin films have a spherical structure, while Al-doped ZnO thin films have a hexagonal-faced rod-like shape. The
bandgap of the prepared thin film reduces with the rise in Al content. The occurrence of deep level and near band edge
emissions were confirmed by photoluminescence (PL) investigations. The maximal zone of inhibition was studied
using the Agar diffusion process on Gram-positive and Gram-negative (i.e., S.aureus and E.coli) bacteria. Pure and
Al-doped ZnO both showed significant antibacterial activity. All the samples exhibit significant antimicrobial activity.
