제목 Light outcoupling enhancement of white organic light-emitting devices with random nano pillar structure
초록 Light outcoupling efficiency of white organic light-emitting device is enhanced by inserting random nano-pillar structure between glass substrate and electrode, which is fabricated by nano-imprint lithography. The angular dependence of light extraction and shift of electroluminescent spectrum are analyzed and compared with the conventional white organic light-emitting device without random nano-pillar structure. An increase in the light outcoupling without affecting the electroluminescent spectrum is achieved.
