Descripción

Descripción general

Europium(III) oxide, also known as europia, is a rare earth metal oxide with high density of 7.42 g/mL at 25 °C. It is widely used in the production of phosphors for cathode ray tubes, X-ray intensifying screens, and fluorescent lamps due to its strong red emission under UV excitation. Europium(III) oxide is a convenient source of europium for doping other metal oxides. Europium doping often imparts fluorescence and photoluminescence, owing to europium’s electron configuration with partially filled f-orbitals. Our high-purity Eu₂O₃ is a key component in the development of energy-efficient lighting and displays, including LED-based technologies.
