What is Erbium oxide used for?
Er2O3 (Erbium (III) Oxide or Erbium Sesquioxide) is used in ceramics, glass, and solid stated lasers. Er2O3 is commonly used as an activator ion in making laser materials. Erbium oxide doped nanoparticle materials can be dispersed in glass or plastic for display purposes, such as display monitors. The photoluminescence property of erbium oxide nanoparticles on carbon nanotubes makes them useful in biomedical applications. For example, erbium oxide nanoparticles can be surface modified for distribution into aqueous and non-aqueous media for bioimaging. Erbium oxides are also used as gate dielectrics in semi conductor devices since it has a high dielectric constant (10–14) and a large band gap. Erbium is sometimes used as a burnable neutron poison for nuclear fuel.
