Abstract: [eng] [cze]
Microwave induced plasma decomposition of iron pentacarbonyl has been used to prepare iron nanosized particles. Vapours of iron pantacarbonyl have been introduced into argon surfaguide discharge, optical mission spectra have been taken and rotational and vibrational temperatures obtained. The temperatures were plotted as a functions of axial and radial distance and of iron pentacarbonyl concentration. Iron nanoparticles have been produced, XRD results and TEM images were obtained. The core-shell nanoparticles were observed, with alpha phase iron as a core and Fe(x)O(y)/C shell. 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.
