Color conversion film comprising inorganic separation layer

A color conversion film which, upon excitation by blue light, emits green and red light;

• the film comprising a multitude of layers whereby,
• one layer is a green light emitting polymer layer comprising green emitting perovskite crystals;
• and
• one layer is a red light emitting polymer layer comprising red emitting coreshell quantum dots comprising Indium and/or Cadmium;
• and
• whereby the red light emitting polymer layer and the green light emitting polymer layer is separated by one or more separating layers;
• characterized in that at least one of said separating layers
• consists of inorganic material;
• and
• is a continuous layer and preferably has a thickness of 1 nm to 10 micrometers;
• and
• covers the whole area of the color conversion film.
