| Outline of Final Research Achievements |
The structure and reactivity of hydrophilic gold oxide films with a thickness of about 1 nm on gold prepared by oxygen glow discharge were investigated using high resolution X-ray photoelectron spectroscopy (XPS) and wavelength modulation surface plasmon resonance (SPR). The gold oxide decomposes in air for a few days but it has two stable oxygen components on the surfaces produced in the early stage of the oxygen glow discharge. The gold oxide reacts with reducing agents in water to decompose. It forms complexes with HCl and HBr and dissolves into the aqueous solutions. It forms aqueous gold hydroxides with bases. It was found that the gold oxide decomposes by water molecules and ultraviolet light and it is stable without them. This unique preservation method of gold oxide developed in the present work contributes to a new hydrophilic surface treatment for gold.
