Abstract
The present invention relates to the field of luminescent crystals (LCs) of the core-shell type, components and devices comprising the same. Particularly, the present invention relates to the manufacturing of luminescent core-shell nanocrystals, wherein said nanocrystal core comprises or consists of a perovskite crystal having a size of 3-100 nm, and said nanocrystal shell comprises a metal oxide having a thickness of 0.5-10 nm and wherein said method comprises combining suitable starting materials under oxygen-free conditions. The invention further provides for specific luminescent core-shell nanocrystals, to components and products containing such luminescent core-shell nanocrystals.
