Description

Erbium trioxide is an important rare earth metal used in biomedicine. It is used as a gate dielectric in semi conductor devices since it 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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
