Abstract
Solid state light emitting devices include a solid state light emitting die and a photonic crystal phosphor light conversion structure. The photonic crystal phosphor light conversion structure may include a solid phosphor layer that includes dielectric nanostructures therein and may be on a light emitting surface of the solid state light emitting die. The photonic crystal phosphor light conversion structure may be attached to the light emitting surface of the solid state light emitting die via an adhesive layer. The photonic crystal phosphor light conversion structure may also be directly on a light emitting surface of the solid state light emitting die. Related methods are also disclosed.
