Abstract: ZnO nanoparticles (ZnO-NPs) were synthesized by precipitation method in three different way i.e. synthesis through mixing the of 1M of zinc sulphate [ZnSO₄] and 2M of potassium hydroxides [KOH] (M₁), through mixing of 0.2M of zinc nitrate [Zn(NO₃)₂] and 0.4M of potassium hydroxide [KOH] (M₂), and by 0.5M of zinc nitrate Zn(NO₃)₂] and 1M of urea [CO(NO₂)₂] (M₃). The synthesized particles were characterized by energy dispersive x-ray spectrometry (EDaX) and UV-Vis spectroscopy. The results of EDaX found that average elemental analysis of nano ZnO particles which were 74.86 weight % and 45.88 atomic % of ZnO-NPs in M₁; 72.11 weight % and 45.51 atomic % in M₂, and 75.04 weight % and 45.69 atomic % of ZnO-NPs in M₃. The optical characterizations of the sample were recorded on UV-Vis indicated three various sample (M₁) red color peck; (M₂) yellow color peck and (M₃) green color peck of synthesis of ZnO-NPs. The band gap energy of the sample is measured by the linear portion of the graph which was confirmed by the presence of excitonic absorption at 380 nm.
