Preparation of black Ag films via a novel thermal evaporation process and comparisons of their properties at the constant thickness and the constant Ag amount
Original language description
Black Ag (B-Ag) films with nanoporous structures were prepared at various Ar gas pressures via thermal evaporation. The structure and properties of the films were compared systematically at a constant thickness of 1 mu m or with a constant amount of Ag atoms of approximately 1.6 x 10-2 mol m-2. The conditions for high optical absorption were also determined. X-ray diffraction (XRD) revealed that the films were polycrystalline. When the films contained a constant amount of Ag atoms, the peak intensity was independent of the Ar gas pressure. Furthermore, their crystallite sizes were not significantly smaller than those of typical films deposited under high vacuum and did not decrease with an increase in the Ar gas pressure. Notably, these features are significantly different from those reported in a previous study. The size change of the nanoparticles observed using a Field Emission Scanning Electron Microscope was consistent with the tendency determined from XRD. The B-Ag films in the present study showed particle formation characteristics similar to those for metal particle formation in the gas phase. In summary, this is the first report of B-Ag films prepared primarily using nucleation in the gas phase rather than on the substrate.
