Abstract: A thin film alloy material with the design of optic reflection and semi-transmission, which not only can make a single layer film have the effect of reflection and semi-transmission simultaneously, but also can attain the effect that has different reflectivity and half-transmittance by adjusting the ratio of alloy and the thickness of thin film. In a thin film that has relative upper and lower surfaces, there are a first alloy layer and a second alloy layer coated on the upper and lower surface; wherein the first alloy layer is composed of silver and metal X, and the metal X is chosen from one of the following metals: titanium, zirconium, hafnium; the second alloy layer is composed of silver, copper, and metal X, and the metal X is chosen from one of the following metals: titanium, zirconium, hafnium.
