SYNTHESIS AND CHARACTERIZATION OF ALUMINIUM DOPED ZnO NANOPARTICLES.

ZnO nanoparticles were synthesized by aqueous solution method.The synthesized particles were characterized by XRD, SEM and EDX .The X-ray diffraction studies reveals that the synthesized ZnO nanoparticles have wurtzite structure and the particle size varies from 11 to 13 nm. A change in morphology from hierarchical nanostructures in ZnO to nanorods after doping with aluminium has been observed. The Energy Dispersive X-Ray Diffraction Spectroscopy (EDX) reveals that the elemental composition of prepared samples and the incorporation of the Al ions into the ZnO lattice. The antibacterial activities of ZnO and Al doped ZnO nanoparticles were examined using the disc diffusion method against four pathogenic bacteria (Eschericia Coli , Klebsiella Pneumoniae , Bacillus Cereus, and Staphylococcus aureus)
