The nanoparticles are characterized by x-ray diffraction and UV-Visible spectroscopy. The x-ray diffraction results reveal that the nanoparticles continue to routine lattice periodicity at reduced particle sizes. The UV-Visible absorption spectrum of the liquid solution of the aluminum nanoparticles shows no characteristic Surface Plasmon Resonance （SPR） peak in the visible region. The TEM and SEM images show that the aluminum nanoparticles have narrow particle size distribution ranged from 20 to120 um with average particle size 80 nm. The aluminum nanoparticles prepared in water and that prepared in ethylene glycol show, no difference in their average particle size and distribution, while those prepared in cyclohexane show smaller sizes. It was observed that the particles have a little irregular shapes and low agglomerate was observed.展开更多
