General description

Erbium(III) oxide (Er₂O₃) is a metal oxide with high thermal stability, optical transparency, and excellent luminescent characteristics. It is widely used in microelectronics, optoelectronics, and biomedical fields. The material is particularly valued for its role in solid-state lasers and optical amplifiers. Additionally, Er₂O₃ is utilized in the production of high-refractive index glasses for optical devices and composite electrolyte for fuel cells.
