Band edge emission enhanced organic light emitting diode with a localized emitter

摘要

A light emitting photonic crystal having an organic light emitting diode and methods of making the same are disclosed. An organic light emitting diode disposed within a photonic structure having a band-gap, or stop-band, allows the photonic structure to emit light at wavelengths occurring at the edges of the band-gap. Photonic crystal structures that provide this function may include materials having a refractive index that varies periodically such as distributed Bragg reflectors, aligned nematic liquid crystals, and holographically recorded gratings.
