A series of single-phase metastable Cu-Ag solid solutions was deposited by magnetron sputtering at liquid-nitrogen temperature. The lattice constant increases with increasing Ag content. The spectroscopic ellipsometer measurements clearly show that with increasing Ag content, the Cu-like and Ag-like absorption edges in the visible wavelength range shift continuously toward the high-energy and the low-energy sides, respectively.
