Synthesis of Yb nanoparticles by laser ablation of ytterbium target in sodium bis(2-ethylhexyl)sulfosuccinate reverse micellar solution

摘要: Abstract Surfactant-coated ytterbium nanoparticles were produced by Nd:YAG laser ablation of a Yb bulk target immersed in sodium bis(2-ethylhexyl)sulfosuccinate (AOT)/ n -heptane micellar solution. In our experimental conditions, as highlighted IR spectroscopy, AOT molecules are not decomposed the intense pulses but play pivotal role stabilisation nanoparticles. The formation liquid phase was monitored UV–Vis spectroscopy whereas Yb/AOT composites obtained evaporation organic solvent characterised XPS and TEM. Data analysis consistently shows presence surfactant-coated, nearly spherical non-interacting mean diameter 3 nm. Moreover, bigger polycrystalline (about 30%) coexistence with smaller mono crystalline ones indicates that, after rapid pristine from plume condensation, two processes effectively compete for their size distribution: nanoparticle agglomeration surfactant adsorption.
