Abstract: A nanoparticle is specified. The nanoparticle comprises a nanocrystal configured to convert electromagnetic radiation of a first wavelength range into electromagnetic radiation of a second wavelength range, a first encapsulation comprising pores which reach into or through the first encapsulation, and a second encapsulation which is different from the first encapsulation, wherein the second encapsulation abuts at least one of the pores. Furthermore, a structure comprising a plurality of nanoparticles and a method for producing nanoparticle is specified.

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.
