Abstract
We have produced nanophase iron clusters inside a gas cell by decompos ing iron pentacarbonyls from the mixture of similar to 20 Torr Fe(CO)( 5)/similar to 3 Torr SF6 with a pulsed CO2 laser. ?The product display ed a black tint. Its composition was identified to be mostly iron from an inductively coupled plasma (ICP) atomic emission spectrum. The X-r ay diffraction (XRD) pattern indicates a body-centered cubic structure for the cluster. A transmission electron micrograph proves that their diameter ranges between 50 and 70 Angstrom and their average diameter is 60 Angstrom.
