Abstract

this work, we report a novel, economical, low temperature solution combustion synthesis (SCS) method to prepare alpha-Al2O3 (Corundum) nanoparticles. Powder X-ray diffraction (PXRD), field emission scanning electron microscopy (FE-SEM), high -resolution transmission electron microscopy (HR-TEM), Fourier transform infrared spectroscopy (FT-IR), BET surface area and ultraviolet visible spectroscopy (UV-vis) measurements were used to characterize the product. Antibacterial studies were examined against gram+ve Klebsiella aerogenes, Escherichia soli, Pseudomonas desmolyticum and gram +ve Staphylococcus aureus bacteria by agar well diffusion method. The alpha-Al2O3 nanoparticles showed substantial effect on all the four bacterial strains. Photoluminescence (PL) measurements under excitation at about 255 nm show that the alumina nanoparticles have emission peaks at 394 and 392 nm.
