Introduction

Nanoparticles research is quickly advancing due to their unique properties, such as having increased electrical conductivity, toughness and ductility, increasing the hardness and strength of metals and alloys, luminescent efficiency of semiconductors, and formability of ceramics.

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

Erbium oxide possesses excellent electrical, optical and photoluminescence properties. Erbium oxide nanoparticles appear in pink powder form. They are graded as irritants, and can cause serious eye irritation. These particles are insoluble in water, and moderately soluble in strong mineral acids.
