Specifications

Erbium Oxide also called Erbia, is an important colorant in glasses and porcelain enamel glazes. High purity Erbium Oxide is widely applied as a dopant in making optical fiber and amplifiers. It is particularly useful as an amplifier for fiber optic data transfer. Erbium Oxide has a pink color and is sometimes used as a colorant for glass, cubic zirconia, and porcelain. The glass is then often used in sunglasses and cheap jewelry.

Application

The applications of Er2O3 are varied due to their electrical, optical, and photoluminescence properties. Nanoscale materials doped with Er+3 are of much interest because they have special particle-size-dependent optical and electrical properties. Erbium oxide doped nanoparticle materials can be dispersed in glass or plastic for display purposes, such as display monitors. The spectroscopy of Er+3 electronic transitions in host crystals lattices of nanoparticles combined with ultrasonically formed geometries in an aqueous solution of carbon nanotubes is of great interest for the synthesis of photoluminescence nanoparticles in ‘green’ chemistry. Erbium oxide is among the most important rare earth metals used in biomedicine. The photoluminescence property of erbium oxide nanoparticles on carbon nanotubes makes them useful in biomedical applications. Erbium oxides are also used as gate dielectrics in semiconductor devices since it has a high dielectric constant (10-14) and a large bandgap. Erbium is sometimes used as a coloring for glasses and erbium oxide can also be used as a burnable neutron poison for nuclear fuel.
