A novel approach to prepare optically active ion doped luminescent materials via electron beam evaporation into ionic liquids

Abstract

A novel approach to prepare luminescent materials via electron-beam evaporation into ionic liquids is presented which even allows doping of host lattices with ions that have a strong size mismatch. To prove this, MgF₂ nanoparticles doped with Eu³⁺ were fabricated. The obtained nanoparticles featured an unusually high luminescence lifetime and the obtained material showed a high potential for application.
