Erbium(III) oxide, is synthesized from the lanthanide metal erbium. 
Erbium(III) oxide was partially isolated by Carl Gustaf Mosander in 1843, and first obtained in pure form in 1905 by Georges Urbain and Charles James.
Erbium(III) oxide has a pink color with a cubic crystal structure. 
Under certain conditions erbium oxide can also have a hexagonal form.
Er2O3 is hygroscopic and will readily absorb moisture and CO2 from the atmosphere.

Erbium Oxide is a highly insoluble thermally stable Erbium source suitable for glass, optical, and ceramic applications. 
Erbium oxide is a solid compound of erbium and is pink in color. Erbium oxide can be also used as a flammable neutron poison for nuclear fuel. 
Erbium Oxide is generally immediately available in most volumes. 
Ultra high purity and high purity compositions improve both optical quality and usefulness as scientific standards. 
Nanoscale elemental powders and suspensions, as alternative high surface area forms, may be considered. 
Erbium has applications in glass coloring, as an amplifier in fiber optics, and in lasers for medical and dental use. 
Rare Earth oxide compounds High Purity (99.999%) Erbium Oxide (Er2O3) Powderare basic anhydrides and can therefore react with acids and with strong reducing agents in redox reactions. 
Erbium Oxide is compounds containing at least one oxygen anion and one metallic cation. 
Erbium Oxide is typically insoluble in aqueous solutions (water) and extremely stable making them useful in ceramic structures as simple as producing clay bowls to advanced electronics and in light weight structural components in aerospace and electrochemical applications such as fuel cells in which they exhibit ionic conductivity. 
Erbium oxide is also available in pellets, pieces, powder, sputtering targets, tablets, and nanopowder (from American Elements' nanoscale production facilities)

One interesting property of erbium oxides is their ability to up convert photons. 
Photon upconversion takes place when infrared or visible radiation, low energy light, is converted to ultraviolet or violet radiation higher energy light via multiple transfer or absorption of energy.
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 successfully made by employing ultrasound are erbium carboxioxide, hexagonal and spherical geometry erbium oxide. 
Each ultrasonically formed erbium oxide is photoluminescence in the visible region of the electromagnetic spectrum under excitation of 379 nm in water. 
Hexagonal erbium oxide photoluminescence is long lived and allows higher energy transitions (4S3/2 - 4I15/2). 
Spherical erbium oxide does not experience 4S3/2 - 4I15/2 energy transitions.

Erbium burns readily to form erbium (III) oxide:
The formation of erbium oxide is accomplished via the reaction 4 Er + 3 O2 → 2 Er2O3.
Erbium oxide is insoluble in water and soluble in mineral acids. 
Er2O3 readily absorbs moisture and carbon dioxide from the atmosphere.
Erbium oxide can react with acids to form the corresponding erbium(III) salts.
For example, with hydrochloric acid, the oxide follows the reaction Er2O3 + 6 HCl → 2 ErCl3 + 3 H2O to form erbium chloride.

Erbium trioxide is an important rare earth metal used in biomedicine. 
Erbium trioxide is used as a gate dielectric in semi conductor devices since Erbium trioxide has a high dielectric constant and a large band gap; as a burnable neutron poison for nuclear fuel and as coloring for glasses. 
Erbium oxide nanoparticles can be surface modified for distribution into aqueous and non-aqueous media for bioimaging due to its photoluminescence property.

Cerium Oxide also called Ceria, is widely applied in glass, ceramics and catalyst manufacturing. 
In glass industry, Erbium oxide is considered to be the most efficient glass polishing agent for precision optical polishing. 
Erbium oxide is also used to decolorize glass by keeping iron in its ferrous state. 
The ability of cerium-doped glass to block out ultra violet light is utilized in the manufacturing of medical glassware and aerospace windows. 
Erbium oxide is also used to prevent polymers from darkening in sunlight and to suppress discoloration of television glass. 
Erbium oxide is applied to optical components to improve performance. 
High purity Ceria are also used in phosphors and dopant to crystal.
