In this work, we report a novel, economical, low temperature solution combustion synthesis (SCS) method to prepare α-Al 2 O 3 (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 coli, Pseudomonas desmolyticum and gram +ve Staphylococcus aureus bacteria by agar well diffusion method. The α-Al 2 O 3 nanoparticles showed substantial effect on all the four bacterial strains. Photoluminescence (PL) measurements under excitation at about 255nm show that the alumina nanoparticles have emission peaks at 394 and 392nm.
