Applications:
Europium(III) oxide (Eu₂O₃) is a high-purity rare earth oxide valued for its exceptional luminescent properties. It is widely used as a red or blue phosphor in television screens, fluorescent lamps, and high-pressure mercury lamps. It serves as an activator for yttrium-based phosphors and as a component in anti-counterfeiting phosphors found in Euro banknotes.
Its applications include:
-
High-efficiency luminescent materials for flat-panel displays
-
Red powder activation for color TV phosphors
-
Dopants for advanced optical materials
-
Fluorescent powder for high-pressure mercury lamps
-
Sintering aid for ceramic and glass production
-
Agent in the manufacture of fluorescent glass
-
Used in lasers, sensors, and high-tech optical devices
With excellent chemical stability and strong emission in the visible spectrum, Europium Oxide is a crucial material for modern photonics, electronics, and display technologies.
