摘要

High quality Al_2O_3 nanoparticles have been successfully synthesized by a simple sol-gel method. Analysis on phase and structure based on x-ray diffraction (XRD) techniques indicate that the as-synthesized samples are well-crystallized γ-Al_2O_3. High-resolution transmission electron microscopy (HRTEM) techniques further confirm a NP is single crystal with size less than 20 nm, the size distribution is uniform as a whole. Raman spectra analysis indicates the vibrational models are in accordance with γ-Al_2O_3. The density of the obtained γ-Al_2O_3 nanoparticles is very small and have a loosen structure. The as-synthesized γ-Al_2O_3 material is comparable to the corresponding products that bought abroad in structure, density and purity, and is suitable for energy saving lamps.
