Abstract

Coupling of light to surface plasmons at metal cathode represents a significant light loss in organic light-emitting diode. The newly discovered graded photonic super-crystals with dual periodicity and dual basis, present great opportunity to improve the light out-coupling (The light extraction efficiency) from organic light-emitting diodes. These graded photonic super-crystals can be holographically fabricated by eight beam interference lithography. In this paper, we have computed, through electrodynamic simulation, the light extraction efficiency of planar, organic light-emitting diodes where the Al cathode is patterned with the graded photonic super-crystals. When the cathode of an organic light-emitting device is patterned in the graded photonic super-crystals, a light extraction efficiency up to 70% in the visible range can be achieved.
