Pulsed laser irradiation of colloidal nanoparticles: a new synthesis route for the production of non-equilibrium bimetallic alloy submicrometer spheres
Abstract
A new one-step approach was developed to synthesize bimetallic alloy submicrometer spheres, which are immiscible under equilibrium, using AuCo as a model system. Uniform, single-phase AuCo alloy submicrometer particles (∼230 nm) with a well-defined spherical morphology were successfully formed via pulsed laser irradiation of Au and Co-oxides nanoparticles dispersed in ethanol and characterized with a combination of electron microscopy, diffraction and magnetization measurements.

Single-phase bimetallic Au-Co alloy synthesized through PLI showed coercivity of 102 Oe at 300 K.
“For instance, the single-phase bimetallic Au–Co alloy has been synthesized through the PLI process using an Nd:YAG laser in ethanol with a pulse fluence and rate of 100 mJ cm−2 pulse−1 and 30 Hz, respectively140. The sub-micrometer particle with an average particle size of 230 nm showed ultimate magnetic properties at a moderate temperature (Coercivity of 102 Oe at 300 K).”

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.
