Claim Text:
1. A light emitting photonic band gab (PBG) material, comprising: (a) a polymer network exhibiting a non-uniform pitch; (b) a small molecule liquid crystal material with a birefringence>0.04; (c) one or more light emitting dyes, herein defined as any electrically or optically excitable material or dye that emits photons having a low triplet state absorption; wherein the non-uniform pitch of the polymer network comprises a uniform chirp, a non-uniform chirp, or a combination thereof; wherein the light emitting PBG material has a defect-induced density of states enhancing feature at a wavelength that overlaps the emission spectrum of the light emitting dye.
