Silver alloy reflecting film with high conductivity and electrochemical corrosion resisting performance and manufacture method thereof

Abstract

A silver alloy reflecting film with high conductivity and electrochemical corrosion resisting performance and a manufacture method thereof are characterized in that the silver alloy reflecting film is an amorphous-state silver alloy reflecting film (3) and contains 0.0001-15 parts by mass of rare earth element and the balance silver element. 0.001-25 parts of one or more of ferrum, cobalt, nickel, tungsten, tin, palladium, gold, rhodium, iridium and ruthenium is further added into the silver alloy reflecting film. In preparation, a glass sheet serves as a substrate (1), chromium, aluminum, titanium, silicon dioxide, the nickel or the ferrum serves as a transition layer (2), and the amorphous-state silver alloy reflecting film (3) is manufactured through vacuum evaporation, magnetron sputtering, ion sputtering, chemical vapor deposition and an electroplating or chemical plating method. The amorphous-state silver alloy reflecting film has the high conductivity and the electrochemical corrosion resisting performance, is simple in manufacture process and is suitable for manufacture of liquid crystal display (LCD) devices, light-emitting diode (LED) devices, organic light emitting diode (OLED) devices, earth current (EC) devices or sensitized solar cell devices.

Description

technical field [0001] The invention relates to a silver alloy reflective film with high electrical conductivity and electrochemical corrosion resistance and a preparation method thereof. Background technique [0002] The electronic structure of rare earth elements is different from that of other elements. Among their atomic electron shells, there is an inner shell that is not filled with electrons—the 4f electron shell. Due to the existence of unsaturated electron shell, rare earth elements have unique characteristics. Adding a small amount of rare earth elements can greatly affect the structure and properties of the material. Rare earth can refine the crystal grains of cast alloys, reduce or eliminate columnar crystals, and expand equiaxed crystal regions. When rare earth elements are added to silver and its alloys, the interfacial tension of the silver alloy liquid can be reduced, the nucleation work of crystal grains can be reduced, the critical nucleus radius can be r...
