Erbium is silver white metal; the melting point is 1529 C, the boiling point is 2863 C, the density is 9.006 g / cm ³ the erbium is antiferromagnetic at low temperature, and it is strong ferromagnetism at the absolute zero degree, and is superconductor. Erbium is oxidized slowly by air and water at room temperature, and erbium is rosy red. Er can be used as reactor control material, erbium can also be used as activator of some fluorescent materials. The first ionization energy is 6.10 electron volts. The chemical properties and physical properties of Ho and Dy are almost the same. Silver gray metallic, soft, insoluble in water, soluble in acids. Salt and oxide are pink to red.

Its oxide Er2O3 is rosy red, used to make glazes of pottery. The ceramic industry uses erbium oxide to produce a pink enamel. Erbium also has some applications in the nuclear industry, and it can also be used as an alloy component of other metals. For example, the incorporation of erbium in vanadium can enhance its ductility. The most prominent use of erbium at present is to manufacture ErbiumDopantFiberAmplifier (EDFA). The bait fiber amplifier (EDFA) was first developed by the University of Southampton in 1985. It is one of the greatest inventions in the optical fiber communication, or even the "gas station" of the long distance information highway. The erbium doped fiber is doped with a small amount of rare earth element erbium ion (Er3+) in the silica fiber, which is the core of the amplifier. The principle of erbium doped optical fiber is that when the Er3+ is stimulated by the light of the wavelength of 980nm or 1480nm to absorb the energy of the pump light, the ground state transitions from the ground state to the high-energy pump state. Because the lifetime of the particle in the pump state is very short, the particle will quickly relax from the pump state to the metastable state in a non radiation way, and the particle has a longer life and accumulates gradually in the energy. When the 1550nm signal is outdated, metastable Er3+ ions are transferred to the ground state in the way of stimulated radiation, and also emit 1550nm wavelength light. The light emitted from the high energy jump to the ground state supplemented the attenuation of the loss of the signal light, thus realizing the signal light being amplified without interruption in the optical fiber propagation process.
