Abstract

The present investigation focuses on the effect of microwave watt power for the synthesis of ZnO nanoparticles (NPs) by microwave irradiation using two different precursors. The prepared samples were confirmed by XRD, SEM and EDXA to analyse the particle size, morphology and chemical composition of ZnO NPs. SEM images were recorded for the synthesis of ZnO NPs from different watt power using different precursors to analyse the morphological changes. The particle size was calculated by Debye-Scherrer formula using XRD pattern. Apart from that, the band gap was calculated from UV spectroscopic technique. The results confirmed that by increasing the watt power ranging from 240 to 420, a wurtzite structure (flower-like) are formed. By changing the zinc acetate with zinc sulphate at various watt powers, the morphology of ZnO NPs changes from spiral to tubular shaped particles were formed.
