摘要:
We report the synthesis of nano-scaled alumina of varied dimensions through an optimized processing of aluminum nitrate. The X-ray diffractometry confirmed the formation of alpha-phase of alumina particles in the nano region, depending on the annealing conditions during processing. Subsequently, a detailed electron microscopy revealed the morphological alterations and crystallographic information even at lattice scale. The band energies were investigated by employing photoluminescence spectrometry. The evolution of fascinating microstructure, phase formations and optical bands has been presented and discussed.
