Erbium Hydroxide also called Erbium Hydrate, is an important colourant in glasses and porcelain enamel glazes. It is particularly useful as an amplifier for fiber optic data transfer. Erbium-doped optical silica-glass fibers are the active element in Erbium-doped fiber amplifiers, which are widely used in optical communications. It is also used for manufacturing halide lamps.
