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 ...
Erbium(III) selenate octahydrate is first dehydrated by heating to obtain the anhydrous form, and then heated continuously to obtain erbium selenite and finally erbium(III) oxide. [1] [2] It can crystallize with M 2 SeO 4 in aqueous solution to form double salts, such as K 3 Er(SeO 4) 3 ·nH 2 O [3] and NH 4 Er(SeO 4) 2 ·3H 2 O, [4] etc.
Naturally occurring erbium (68 Er) is composed of six stable isotopes, with 166 Er being the most abundant (33.503% natural abundance).Thirty-nine radioisotopes have been characterized with between 74 and 112 neutrons, or 142 to 180 nucleons, with the most stable being 169 Er with a half-life of 9.4 days, 172 Er with a half-life of 49.3 hours, 160 Er with a half-life of 28.58 hours, 165 Er ...
