Europium Oxide (Eu2O3) Nanoparticles - Properties, Applications

The prospects for using nanomaterials with diameters of <100 nm in a number of applications is being widely researched around the world today.

This article discusses the properties and applications of europium oxide nanoparticles. Europium is a Block F, Period 6 element, while oxygen is a Block P, Period 2 element.

Europium oxide nanoparticles appear in white powder form. They are graded as an irritant, and can cause skin, eye, and respiratory irritations. These particles are insoluble in water, and moderately soluble in strong mineral acids.
