Neodymium Oxide (Nd2O3) Nanoparticles - Properties, Applications

Nanoparticles are being custom-made to suit various applications across multiple domains such as cosmetics, optical components, biology, physics, chemistry, polymer science, pharmaceutical drug manufacture, toxicology, and mechanical engineering.

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

The morphology of neodymium oxide nanoparticles is spherical, and they appear in a purple powder form. They absorb moisture and carbon dioxide in air, and do not dissolve in water but dissolve in acid.
