Disclosed herein are light emitting devices comprising a series of photopolymerizable chiral liquid crystalline layers that can be solvent cast onto a substrate, and methods of making such devices. The mixture of chiral materials in each successive layer can be blended in such a way that each layer has the same chiral pitch. Furthermore, the chiral material in each layer can be further blended such that the ordinary and extraordinary refractive indices in each layer match the other layers, so that the complete organization of the layers Will function as a single, relatively thick layer of chiral liquid crystal. The chiral nematic material in each layer can spontaneously take the form of a helical structure with a helical pitch. The light emitting layer of the light emitting device may further comprise an electroluminescent material that emits light into the band edge light propagating mode of the photonic crystal.
