ALUMINIUM - MODIFIED ZNO NANOPARTICLES SYNTHESIZED THROUGH CO-PRECIPITATION

Abstract

The co-precipitation method is commonly used to produce nanoscale particles. The method was used to produce undoped and aluminium (Al) doped Zinc Oxide (ZnO) nanoparticles with doping percentages of 0 at%, 1 at%, 3 at%, and 5 at%. The samples were thermally treated in an atmospheric environment at 600 °C. The samples are then subjected to a number of characterization processes in order to investigate the effect of Al doping on the crystal structures, morphology, and chemical composition of the particle’s surfaces. The doping process results in a polycrystalline structure of the Al doped ZnO with a predominant peak in the (101) phase. Furthermore, as doping content increased, the peak intensities of the (101) phase decreased. The results of the morphology through the field effect electron microscopy (FESEM) reveals the Al doping have a significant impact on the prepared samples.
