Erbium electronic structure

ADXD spectrum, 304/ electronic structure, 301 equations of stale, 305, 305/ 30 phase transition, 301 302 erbium... 

The cost of 99.9% erbium metal is about 21/g. Erbium is finding nuclear and metallurgical uses. Added to vanadium, for example, erbium lowers the hardness and improves workability. Most of the rare-earth oxides have sharp absorption bands in the visible, ultraviolet, and near infrared. This property, associated with the electronic structure, gives beautiful pastel colors to many of the rare-earth salts. Erbium oxide gives a pink color and has been used as a colorant in glasses and porcelain enamel glazes. 

Erbium has a total of 11 electrons in its 4f shell. The crystal structure sequence hcp Sm-type dhcp dfcc seen in lanthanide metals with decreasing atomic number and increasing pressure is also observed in erbium.
