Beschreibung
Zusammenfassung:	Composition and films for light emitting devices are disclosed. An example film may comprise at least one polymer layer comprising a first polymer and a second polymer. The second polymer may exhibit partial miscibility with respect to the first polymer. The partial miscibility of the first polymer relative to the second polymer may be greater than 0% miscibility and less than 100% miscibility. The film may comprise a plurality of stabilized quantum dots comprising a first portion of quantum dots that emit light in a first wavelength range upon excitation and a second portion of quantum dots that emit light in a second wavelength range upon excitation. The first portion of the plurality of stabilized quantum dots may be disposed in the first polymer and the second portion of the plurality of stabilized quantum dots may be disposed in the second polymer.
