Cobalt oxide thin films prepared by chemical vapor deposition from cobalt (II) acetate

Abstract

Cobalt oxide thin films were prepared by a low-temperature atmospheric-pressure chemical vapor deposition method. The raw material was cobalt (II) acetate which is non-toxic and easy to handle. Polycrystalline films were obtained at a reaction temperature above 300°C. From near-normal reflection measurements it follows that the films have solar absorptance α = 0.73 and thermal emittance ϵ = 0.089.
