Synthesis of Fe2O3 thin films

What is it about?

We propose an efficient and low-cost synthesis of a Fe(II) complex, to be used in the Chemical Vapor Deposition (CVD) of nanostructured Fe2O3 thin films. The compound is monomeric, has a octahedral structure, and possesses a remarkable air stability and a high volatility at moderate temperatures.

Why is it important?

Good precursors (molecular sources) for nanostructures by chemical-vapor-deposition should have sufficient volatility, a high thermal stability and a clean decomposition pathway. No such precursors were available for the deposition of iron oxide materials. In this work, a Fe(II) precursor possessing just those amenable features was synthesized and successfully tested in the CVD growth of iron oxide nanostructures.

Chemical vapor deposition (CVD) is a widely-used approach for the preparation of novel materials. Iron oxide materials are becoming increasingly relevant for diverse technology fields. Our Fe(II) complex was indeed a very successful precursor for growing iron oxide nanostructure, as demonstrated by several follow-up studies by different research groups. Various Fe2O3-based materials, with applications in gas sensing and H2-production have already been realized starting from our precursor, and many other could follow, driven by the increasing interest toward iron oxide materials.
