Abstract

A wavelength converter material and a method of A method of preparing a wavelength converter material may include providing an optionally oxide coated phosphor material, mixing the optionally oxide coated phosphor material with an optionally oxide coated paramagnetic nanoparticle, coating the optionally oxide coated phosphor material and the optionally oxide coated paramagnetic nanoparticle with an oxide coating, thereby preparing a coated phosphor-nanoparticle particle, and separating the coated phosphor-nanoparticle particle, thereby preparing a wavelength converter material. The separating of the coated phosphor-nanoparticle particle may be manipulated by applying a magnetic field. Furthermore, a wavelength converter material, as well as a light emitting diode are described herein.
