Iron oxide nanoparticles (NPs) were prepared by green synthesis process, using Pheonix Dactylifera. L. leaves ethanolic extractas polyphynols source and FeCl3 aqueous solution as precursor, where the volume ration was 1:2. The concentration of FeCl3 was varied as follow: (0.01, 0.02, 0.03 and 0.04M). To charactrizethe obtained iron oxide NPs, XRD, SEM, UV-VIS and FTIR techniques were used. XRD analyses show the existence of three essentials compounds of iron oxide NPs: maghemite phase, hematite phase and beta phase. While the grain size of these compoundswas varied in the ranges of 22.91-37.40nm, 20.41-31.32nm and 17.96-25.25nm respectively. SEM images analysis showed that all samples have spherical shaped particles. UV-VIS analysis showed that the variation of FeCl3 concentration hasdirecteffect on theband gap of the product which rangeedin the range 2.162-2.358eV, whereas FTIR study confirms the abundance of Fe-O bonds in all samples.
