High Quality Al₂O₃ Nanoparticles Used for Energy Saving Lamps

Abstract:

High quality Al2O3 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-Al2O3. 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-Al2O3. The density of the obtained γ-Al2O3 nanoparticles material is very small and have a loosen structure, elemental analysis suggests that the nanoparticles are high purity. The as-synthesized γ-Al2O3 material is comparable to the corresponding products that bought abroad in structure, density and purity, and is suitable for energy saving lamps.
