    摘要： Described are luminescent components with excellent performance and stability. The luminescent components comprise a first element 1 including first luminescent crystals 11 from the class of perovskite crystals, embedded a first polymer P1 and a second element 2 comprising a second solid polymer composition, said second polymer composition optionally comprising second luminescent crystals 12 embedded in a second polymer P2. Polymers P1 and P2 differ and are further specified in the claims. Also described are methods for manufacturing such components and devices comprising such components.

    摘要： A luminescent component comprises a first film comprising a first solid polymer composition and a second film comprising a second solid polymer composition. The first solid polymer composition comprises first luminescent crystals. The second solid polymer composition comprises second luminescent crystals. The first luminescent crystals are of size between 3 nm and 3000 nm, and emit red light in response to excitation by light with a shorter wavelength. The second luminescent crystals are of size between 3 nm and 3000 nm, and emit green light in response to excitation by light with a shorter wavelength. Said luminescent component is particularly suited for the application in LCD-backlight color conversion.

    摘要： The invention refers in a first aspect to a solid polymer composition (100) comprising green luminescent crystals (1), non-perovskite red phosphor particles, and a polymer (3). The polymer (3) has a molar ratio of the sum of (oxygen+nitrogen) to carbon z, wherein z≤0.9, z≤0.75 in particular z≤0.4, in particular z≤0.3, in particular z≤0.25. A second aspect of the invention refers to a self-supporting film comprising the solid polymer composition (100) of the first aspect. A third aspect of the invention refers to a light emitting device comprising either the solid polymer composition (100) according to the first aspect of the invention or the self-supporting film according to the second aspect of the invention.
