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.
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 ...
Erbium oxide nanoparticles also possess photoluminescence properties. Erbium oxide nanoparticles can be formed by applying ultrasound (20 kHz, 29 W·cm −2) in the presence of multiwall carbon nanotubes. The erbium oxide nanoparticles that have been produced using ultrasound are erbium carboxioxide, hexagonal and spherical geometry erbium oxide.
