The Cookies Statement is part of our Privacy Policy. When alloyed with metals such as vanadium, erbium lowers their hardness and improves their workability. The rare earths were revealed to the world quite by accident by a Swedish lieutenant and rock-hound Carl Axel Arrhenius in 1787 in a quarry on the island of Vaxholm in Sweden, where the small town of Ytterby is located. Erbium has no known biological role, and has low toxicity. But much like light passing through the atmosphere, scattering occurs - photons of light collide occasionally with the chains of glass in the fibre and the light is attenuated, limiting the length of fibre one can use. It was a stunning example of the luminescence of the group of elements, the rare earths, of which erbium is a member. He pulled out of his pocket a sample vial containing some stunning pink crystals that glinted alluringly.
