Spectroscopic characterisation and antibacterial activity of ZnOnanosheets

Abstract

This paper describes an easy synthesis of zinc oxide (ZnO) nanosheets using triethylamine (TEA) as a complexing agent withzinc sulphate hexahydrate as a zinc source. The as-formed zinc triethylamine complex was calcined at 600C for 6 h to get ZnOnanosheets. The synthesised sample was characterised by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), UVevisible(UVeVis), energy dispersive X-rays (EDS) spectroscopy, scanning electron microscopy (FESEM) and high resolution trans-mission electron microscopy (HR-TEM). The antibacterial activity of ZnO nanosheets was evaluated using agar diffusion method.The results suggest that the synthesised ZnO nanosheets will be a promising candidate in the field of biomedical application.
