<p>Disclosed is an alloy as a material for forming a reflective/transmissive film used in display devices, building materials, illuminating devices and the like, which alloy is able to function for a long time without suffering from decrease in reflectance. Specifically disclosed is a silver alloy excellent in reflectance and transmittance which is mainly composed of silver while containing at least one noble metal selected from platinum, palladium, gold, rhodium and iridium as first additional elements. Platinum, palladium and gold are preferable as the first additional elements, and it is further preferable to add at least one element selected from gallium, copper and dysprosium as second additional elements. The total concentration of these additional elements is preferably 0.01-20.0 atom%.</p> |
