Ytterbium sesquioxide, Yb2O3

Ytterbium sesquioxide (Yb2O3) is a chemical compound formed from ytterbium and oxygen. This white, crystalline oxide is one of the primary compounds of ytterbium and serves as a common precursor in the preparation of other ytterbium salts. Its high melting point and stable nature make it a suitable material for certain specialized applications. In the realm of optics and photonics, Yb2O3-doped materials are of interest for their lasing properties, especially when doped into laser host materials. The compound is also researched in the context of high-temperature superconductors and other advanced materials. Being an oxide of a rare-earth element, Yb2O3 shares many characteristics typical of the lanthanide series, including its ability to form complex coordination compounds.
