Iron oxide nanoparticles (NPs) have been extensively used for both health and technological applications. The control over their morphology, crystal microstructure, oxidation state is of great importance to optimize final use. However, while mature in understanding, it still far from complete. Here we report on the effect amount 1,2-hexadecanediol and/or 1-octadecene reaction mixture thermal decomposition iron(III) acetylacetonate oleic acid two series iron NPs with sizes ranging 6 48 nm. We...

The key role of the structural defects on magnetic properties cobalt ferrite nanoparticles (NPs) is investigated by complementary local probes: element- and site-specific X-ray circular dichroism (XMCD) combined with high-resolution transmission electron microscopy individual NPs. A series monodisperse samples 8 nm NPs a tunable amount were prepared thermal decomposition Fe(III) Co(II) acetylacetonates in presence variable concentration 1,2-hexadecanediol. particles show partial inverse...

We report on the controlled synthesis and functionalization in two steps of elongated Bi2S3 nanoparticles within a wide range sizes. First, we show effect temperature reaction time series by thioacetamide with bismuth(III) neodecanoate presence organic surfactants. At 105 °C long times, nanoneedles about 45 nm length containing larger crystallites are obtained, while highly crystalline nanorods 30 dominant at 165 °C, regardless time. The optical properties both types an enhancement band gap...
