Preparation of metal oxide-based nanomaterials using nanosecond pulsed laser ablation in liquids

Numerous experiments for nanomaterial fabrication using pulsed laser ablation in liquid have been reported. Most studies have focused on the formation of noble-metal nanoparticles and their surface plasma-resonant optical properties. This short review highlights the fabrication of metal oxide-based nanomaterials such as oxide and hydroxide nanoparticles, as well as layered nanocomposites, via nanosecond pulsed laser ablation of metallic target materials in water and aqueous surfactant solutions. These crystallized oxide-based nanomaterials are formed through the ejection of ablated species with extremely high density and high kinetic energy followed by oxidation in the liquid.
