Application
Erbium oxide for phosphor also called Erbia, an important colourant in glasses and porcelain enamel glazes. High purity erbium oxide for phosphor are widely applied as dopant in making optical fibre and amplifier. It is particularly useful as an amplifier for fiber optic data transfer. erbium oxide for phosphor 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. Erbium oxide isused for making yttrium iron garnet admixtures and control materials for nuclear reactors, metal and electronic industries.
