Photoluminescence of ZnO nanoparticles prepared by laser ablation in different surfactant solutions

Article Abstract:

The study prepared ZnO nanoparticles by laser ablation of a zinc plate in a liquid environment using different surfactant solutions. It concluded that anionic oxygen in the amphoteric molecules effectively occupied the oxygen vacancy sites at the ZnO nanoparticles surface due to charge with the positively charged ZnO nanoparticles.

Synthesis of ultrafine SnO(sub 2-x) nanocrystals by pulsed laser-induced reactive quenching in liquid medium

Article Abstract:

Synthesis of ultrafine tin oxide nanocrystals (2 to 3 nm) by pulsed laser ablation of a tin metal plate in aqueous solutions of sodium dodecyl sulfate (SDS) and in pure water is presented. A possible formation process of tin oxide is proposed based on laser-induced reactive quenching and surfactant-mediated growth.

Au-mediated growth of wurtzite ZnS nanobelts, nanosheets, and nanorods via thermal evaporation

Article Abstract:

The large-scale synthesis of wurtzite ZnS nanobelts by simple thermal evaporation of ZnS powder at a relatively lower temperature of 970-degree Celsius, in the presence of Au catalysts, is presented. The characterization, growth process, and photoluminescence properties of the ZnS nanostructures are discussed.
