摘要： A structure may include a quantum structure and a barrier layer that may coat the quantum structure. The barrier layer may include aluminum and at least one material that is X1, X2, Si, O, or combinations thereof where X1 and X2 are monovalent positively charged elements and/or divalent positively charged elements. In addition, an agglomerate, a conversion element, and a method of producing a structure are disclosed.

摘要： 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.
