Preparation of Oxide Nanomaterials Using Pulsed Laser Ablation

Abstract

Pulsed laser ablation (PLA) in gas and liquid media is an extremely powerful technique for the fabrication of crystallized oxide nanomaterials such as nanoparticles of simple and complex oxides, and organic/inorganic nanocomposites without post annealing or substrate heating. The Fe₂0₃, CO₃0₄ and BaTiO₃ nanoparticles were prepared by PLA of corresponding oxide targets in inert gas atmosphere. Nanoparticles of TiO₂, SnO₂and Zinc hydroxide/dodecyl sulfate nanocomposite were prepared by PLA of corresponding metal target inaqueous solutions. The formation mechanisms of the obtained nanomaterials are also discussed.
