Erbium is a rare earth metal widely used as a dopant in fiber optic amplifiers and lasers for telecommunications.
Properties of Erbium | It exhibits +3 oxidation state and provides emission at wavelengths ideal for optical communications around 1.5 ?m.
Uses of Erbium | Key use as erbium doped fiber amplifiers EDFAs, in lasers, glass coloring and metallurgical applications.
Isotopes of Erbium | Stable isotopes include Er 166 to Er 170; erbium compounds are of low acute toxicity and handled with routine precautions.
