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.
The storeroom is ventilated and dried at low temperature.
