Characteristic
Europium(III) oxide (Eu2O3), is a chemical compound of europium and oxygen.
Chemical formula：Eu2O3
Molar mass： 351.926 g/mol
Appearance： white to light-pink solid powder
Odor： odorless
Density： 7.42 g/cm3
Melting point： 2,350 °C (4,260 °F; 2,620 K)
Boiling point： 4,118 °C (7,444 °F; 4,391 K)
Solubility in water：Negligible
Magnetic susceptibility (χ)：+10,100·10−6 cm3/mol
Thermal conductivity： 2.45 W/(m K)
Crystal structure：Monoclinic, Cubic
Application
It is widely used as a red or blue phosphor in television sets and fluorescent lamps, and as an activator for yttrium-based phosphors. It is also an agent for the manufacture of fluorescent glass. Europium fluorescence is used in the anti-counterfeiting phosphors in Euro banknotes.
