Europium oxide

Eu2O3 - Rare earth for phosphors, displays and nuclear technology
Europium oxide (Eu₂O₃) is a fine, light pink powder from the group of rare earths. Due to its pronounced luminosity when excited with UV or X-rays, it is used in the production of red phosphors for screens, LEDs and fluorescent lamps. Europium oxide is also valued in nuclear technology and in the optical industry due to its special absorption and transmission properties.
PROJECTOR supplies industrial-grade europium oxide for customers in the lighting technology, glass processing and research sectors - with short delivery times and REACH-compliant documentation.
Typical areas of application:
The main areas of application are in electronics and energy technology. Europium oxide is mainly used as an activator in phosphors, which are used in LED chips, flat screens, fluorescent lamps and medical and analytical devices. It is also suitable for doping glass fibers and for neutron-absorbing materials in reactor technology.
