| abstract |
The invention refers in a first aspect to a solid polymer composition (100) comprising green luminescent crystals (1), red luminescent crystals (2), and a polymer (3). The green luminescent crystals (1) are perovskite crystals. The red luminescent crystals (2) are zincblende or wurzite, preferably zincblende, crystals. n A second aspect of the invention refers to a self-supporting film comprising the solid polymer composition (100). n A third aspect of the invention refers to a light emitting device comprising either the solid polymer composition (100) or the self-supporting film. |
