Erbium's principal uses involve its pink-colored Er 3+ ions, which have optical fluorescent properties particularly useful in certain laser applications. Erbium-doped glasses or crystals can be used as optical amplification media, where Er 3+ ions are optically pumped at around 980 or 1480 nm and then radiate light at 1530 nm in
Erbium(III) chloride hexahydrate also forms monoclinic crystals with the point group of P2/n (P2/c) - C 4 2h. In this compound, erbium is octa-coordinated to form [Er(H 2 O) 6 Cl 2] + ions with the isolated Cl − completing the structure. [13] Erbium(III) bromide is a violet solid.
Erbium iodate is an inorganic compound with the chemical formula Er(IO 3) 3. Preparation. Erbium iodate can be obtained by reacting erbium periodate and periodic ...

The bell-like sounds of a celesta correspond to edits with a net addition of content to Wikipedia, and the strums of a clavichord correspond to net subtractions of content. The pitch is inversely proportional to the size of the edit (lower pitched notes are produced by larger edits). [6] Newly registered Wikipedia users are welcomed by a string ...
