Abstract

Preparation of Zinc Oxide (ZnO) thin films by modified Chemical Bath Deposition is known as Successive Ionic Layer
Adsorption and Reaction (SILAR) method. The structural , optical properties, antibacterial and antifungal activities were studied for different post annealing temperature. X-Ray Diffraction (XRD) pattern confirms the crystalline nature and it exhibits hexagonal structure along with c-axis orientation. Field Emission Scanning Electron Microscope (FESEM) confirms the occurrence of a floral pattern and pinhole-free film. Energy Dispersive X-ray (EDAX) results confirms the existence of zinc and oxygen atoms. Optical properties were examined using UV-Visible spectroscopy. The band gap decreases as the annealing temperature increases from250°C to 450°C. Antibacterial activities against E. coli (Gram-negative) show the maximum zone of inhibition when compared to S.aureus (Gram-positive). Antifungal activities against Aspergillussp were also studied.
