-Fe Nanoparticles Prepared by Microwave Plasma Decomposition of Iron Pentacarbonyl
Original language description
The nanocrystalline iron powder has been prepared by the introducing of Fe(CO)5 vapor into the microwave induced argon discharge. A microwave 2.45 GHz source was operated at 430 W. The reaction was performed in a quartz tube passing through the microwavewaveguide. The in-situ passivation using air was applied after synthesis. The powder was characterised by TEM, XRD, and Mössbauer spectroscopy. According to our TEM investigation, the produced passivated powder included aggregated core-shell nanoparticles. The cores consist of -Fe and the shell is supposed to be iron oxide (indicated by TEM). The presence of -Fe and iron oxides was confirmed by XRD and Mössbauer spectroscopy. The mean coherence domain size of -Fe cores was estimated to be 30 nm. The synthesized nanopowder exhibits ferromagnetic behaviour.

-Fe nanočástice připravené rozkladem pentakarbonylu železa v mikrovlnném výboji
Czech description
Použili jsme dekompozici pentakarbonylu železa v mikrovlném plazmatu pro přípravu železných nanočástic. Páry pentakarbonylu železa byly přidány do argonového výboje v surfaguide. Byla změřena optická emisní spektra a spočítány rotační a vibrační teploty.Teploty byly určeny v závislosti na koncentraci pentakarbonylu železa a na axiální a radiální vzdálenosti. Získané nanočástice byly analyzovány pomocí RTG difrakce a TEM. Byly pozorovány nanočástice se strukturou jádro-slupka, kde alfa-Fe fáze tvořila jádro a Fe(x)O(y) nebo C tvořily slupku částice.
