Europium Sputtering Targets are circular targets of europium metal available in 3 different sizes. Europium is a rare earth metal with unique magnetic and optical properties. These disks are ultra-high purity (99.9%) europium, ideal for thin film deposition and coating applications where its fluorescent and phosphorescent capabilities are desired, such as in LEDs, lasers, phosphors and europium-doped glasses. Our Europium Sputtering Targets provide flexibility for integration into various vacuum deposition systems.
