A versatile single-source precursor for the synthesis of LaCoO3 films

The present communication is focused on the synthesis of the versatile heterobimetallic LaCo(ODiEt)5 (ODiEt = OC(CH2CH3)2CH2OCH3) alkoxide compound and on its innovative and unprecedented use as single-source precursor in the preparation of LaCoO3 films by both sol–gel and Chemical Vapour Deposition techniques. Nanostructured LaCoO3 films characterized by thermal stability of the perovskite structure up to 900 °C have been obtained thus evidencing the versatility of the adopted source compound. Morphological analysis revealed that high-quality smooth, well-adherent and crack-free layers have been prepared.
