Beschreibung
Erbium(III) oxide (Er2O3) is a member of rare-earth sesquioxides. Er2O3 powder has a pink appearance and the crystal structure of the material is generally known to be cubic. Erbium oxide found to be insoluble in water and soluble in mineral acids. Er2O3 provides various excellent properties such as high dielectric constant (≈14), high mechanical strength, high chemical and thermal stability in contact with Si, wide bandgap (~5.4 eV), substantial hardness and high transparency in visible light.
Chemische Eigenschaften
Pink powder that readily absorbs moisture and carbon dioxide from the atmosphere. infusible. Insoluble in water; slightly soluble in mineral acids.
Erbium(III) oxide (Er2O3), a pink solid, is a compound of erbium sometimes used as a colouring for glasses and a dopant for optical fibres and optical amplifiers. It was partially isolated by Carl Gustaf Mosander in 1843, and first obtained in pure form in 1905 by Georges Urbain and Charles James.
Verwenden
Erbium(III) oxide is used for vacuum deposition electrical, optical and photoluminescenc, gate dielectrics in semi conductor devices, and in Biomedicine.
Application
Erbium(III) oxide are utilized in different applications such as protective materials and in corrosion-resistant coatings, electrically insulating coating material, sensing membranes for pH detection, alternative gate oxides to replace silicon oxide in metal oxide semiconductor devices, display monitors, optical communication, Hall effect sensors, imaging in biological systems, and probing solution complexation properties. Furthermore, Er2O3 exhibits a good catalytic performance during the oxidative dehydrogenation of ethane to ethylene.
