Fabrication and Size-Dependent Optical Properties of FeO Nanoparticles Induced by Laser Ablation in a Liquid Medium
Abstract
We report the fabrication of FeO nanoparticles by pulse laser ablation of pure iron plate in the poly(vinylpyrrolidone) solutions. It has been found that the particle size can be controlled in a wide range from 45 to 5 nm by the surfactant concentration from 0.01 to 0.2 M. The optical absorption measurements of the obtained colloidal solutions show that the optical absorption edge red shifts with reduction of the particle size and exhibits the optical features of the semiconductor with indirect band gap. The red shift is attributed to lattice defects in the nanoparticles. This study shows that pulse laser ablation in liquid media is a good method to synthesize some nanoparticles with special structures, which are difficult to produce by other conventional methods.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
