Introduction

Nanoparticles research is a quickly developing area with immense potential in a variety of fields such as optical, biomedical, and electronic fields.

Europium is a Block F, Period 6 element. It is a ductile metal with a hardness that is similar to that of lead. It readily oxidizes in air and water. Europium nanoparticles appear as a silvery powder. Europium nanoparticles are graded as highly flammable with the capacity to catch fire spontaneously if exposed to air.
