Formation and Characteristics of Cu Colloids from CuO Powder by Laser Irradiation in 2-Propanol
Abstract
The laser ablation technique has been employed to prepare Cu colloids from CuO powder in 2-propanol using wavelengths of 1064 and 532 nm. The copper colloids resulting from 1064 nm irradiation were conspicuously stable under aerobic conditions without any protective agent present. In addition to Cu particles, the formation of oxidized product, acetone, from 2-propanol was detected by gas chromatography. The discrepancy in the Cu colloidal formation between 1064 and 532 nm was analyzed on the basis of the absorptive ability of CuO powder, the results of the power dependence, and the measurements of the dose effect. The process of photoinduced coalescence that formed larger spherical particles was found to be wavelength-dependent. The stability of the Cu colloids could be the result of their near-perfect spherical shape and the effect of their larger size.

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.
