The invention discloses color conversion film which, upon ex-citation by blue light, emits green and red light. The films comprise at least one red light emitting layer, one green light emitting layer and sandwiched in between at least one separation layer.

Color conversion film with separation layer

The present invention relates to the field of luminescent crystals (LCs), and more specifically to Quantum Dots (QDs) of formula AMX, wherein the substituents are as defined in the specification. The invention provides methods of manufacturing such luminescent crystals, particularly by dispersing suitable starting materials in the presence of a liquid and by the aid of milling balls; to compositions comprising luminescent crystals and to electronic devices, decorative coatings; and to components comprising luminescent crystals.

Luminescent crystals and manufacturing thereof

The present invention relates in a first aspect to a solid polymer component comprising luminescent crystals of 3-500 nm size, surfactant and a hardened/cured polymer. In a second aspect of the invention, a luminescent component comprises a first element comprising the solid polymer component according to the first aspect and an encapsulation enclosing the first element. In a third aspect of the invention, a luminescent component comprises a first film comprising the solid polymer composition of the first aspect. A fourth aspect of the invention relates to a light emitting device comprising the luminescent component according to the second or third aspect of the invention and a light source.
