A color conversion film is provided which, upon excitation by blue light, emits green and red light. The color conversion films include at least one red light emitting layer, one green light emitting layer and sandwiched in between at least one inorganic separation layer. The green light emitting layer includes green emitting perovskite crystals.

Color conversion film comprising inorganic separation layer

Described are luminescent components with excellent performance and stability. The luminescent components comprise a first element including first luminescent crystals from the class of perovskite crystals, embedded a first polymer Pand a second element comprising a second solid polymer composition, said second polymer composition optionally comprising second luminescent crystals embedded in a second polymer P. Polymers Pand Pdiffer and are further specified in the claims. Also described are methods for manufacturing such components and devices comprising such components.
